# The Time Tunnel

The Time Tunnel is an American color science-fiction television series written around a theme of time travel adventure; it starred James Darren and Robert Colbert. The show was creator-producer Irwin Allen's third science-fiction television series and was released by 20th Century Fox Television and broadcast on ABC. The show ran for one season of 30 episodes from 1966 to 1967. A new pilot was produced in 2002, but failed to proceed to a series.

## Premise

Project Tic-Toc is a top-secret U.S. government effort to build an experimental time machine, known as "The Time Tunnel" due to its appearance as an elliptical passageway. The base for Project Tic-Toc is a huge, hidden underground complex in Arizona, 800 floors deep and employing more than 12,000 specialized personnel. The directors of the project are Dr. Douglas Phillips (Colbert), Dr. Anthony Newman (Darren), and Lt. General Heywood Kirk (Whit Bissell). The specialists assisting them are Dr. Raymond Swain (John Zaremba), a foremost expert in electronics, and Dr. Ann MacGregor (Lee Meriwether), an electrobiologist supervising the unit that determines how much force and heat a time traveler is able to withstand. The series is set in 1968, two years into the future from the actual broadcast season, 1966–1967.
Project Tic-Toc is in its 10th year when United States Senator Leroy Clark (Gary Merrill) comes to investigate to determine whether the project, which has cost $7.5 billion (equivalent to $68 billion in 2024), is worth continuing. Senator Clark feels the project is a waste of government funds. When speaking to Phillips, Kirk, and Newman in front of the Time Tunnel, he delivers an ultimatum – either they send someone into time and return him during the course of his visit or their funding will cease. Tony volunteers for this endeavor, but he is turned down by project director Doug Phillips. Defying this decision, Tony sends himself into time. Doug follows shortly after to rescue him, but they both continue to be lost in time. Senator Clark returns to Washington with the promise that funding will not be cut off to the project, leaving General Kirk in charge.
The stage is set for the progress of the series as Tony and Doug are now "switched" from one period in history to another, allowing episodes to be set in the past and future. Episodes two through 23 begin with the following narration (voiced by Dick Tufeld):
   Two American scientists are lost in the swirling maze of past and future ages, during the first experiments on America's greatest and most secret project, the Time Tunnel. Tony Newman and Doug Phillips now tumble helplessly toward a new fantastic adventure, somewhere along the infinite corridors of time.
Tony and Doug become participants in past events such as the sinking of the Titanic, the attack on Pearl Harbor, the eruption of Krakatoa, Custer's Last Stand, and the Battle of the Alamo, among others. General Kirk, Ray, and Ann in the control room are able to locate them in time and space, observe them, occasionally communicate with them through voice contact, and send help. The series was abruptly cancelled in the summer of 1967 by ABC, before they were able to film the episode in which Tony and Doug are safely returned to the Time Tunnel complex.

## Possibility of time travel

According to the plot, time travel is facilitated by time being portrayed as a static continuum, accessible at any point through the Time Tunnel as a corridor spanning its infinite reaches. When Senator Clark sees an image of the Titanic on the image screen in the course of episode one, he is told by Dr. Swain that he is seeing "the living past", and Althea Hall is told by Tony Newman that the past and the future are the same. The Time Tunnel is also a portal connecting the Time Tunnel "complex" with the same time periods in which Doug and Tony are located. Other people can also be relocated by the Time Tunnel from their time to another time as Machiavelli is switched from his own time to the time of the Gettysburg Campaign of 1863. Bringing people (other than Tony and Doug) to the present happens often in the series, but the only occasion in which Tony and Doug return to their own time occurs in "Merlin the Magician", when the great wizard uses magic to bring them home in suspended animation so he can instruct them to perform a mission for him.
In the course of the series, Doug, Tony, and the Time Tunnel personnel discover that events of the past can be altered to some extent by the intrusion of the time travelers, and in a few cases, their historical research allows for it. Episode 26 ("Attack of the Barbarians") explores the scenario of one of the time travelers falling in love with someone from the past: Tony and the Princess Serit, daughter of Kublai Khan. Marco Polo tells Doug, "Can they not touch each other?" History itself hints at the possibility of Serit marrying Tony as Ann informs General Kirk. The historical information on Billy the Kid's victims alarms Ann, Ray, and the General, as it records that he killed two strangers near Lincoln, New Mexico, in April 1881—just when Tony, Doug, and Billy the Kid are brought together.

## Production

The production used sets, stock footage, and props left over from the large number of period dramas made by the 20th Century Fox film company. Even black-and-white shots purporting to show the Titanic sinking were tinted for use in this color production. Only a few actors were costumed for a given episode, interspersed with cuts of great masses of people similarly dressed from original features. Only one set was constructed for the show, that of the Time Tunnel's main control room. For the pilot episode, a large control-room set was built, and a longer Time Tunnel was created using optical matte shots. After the pilot episode, location changes occurred for the production of the series; Colbert and Darren shot their scenes in another studio, on the 20th Century Fox backlot, or on location, while those who portrayed the Time Tunnel personnel filmed all their scenes on a revised and smaller Time Tunnel control-room set (due to the production having to use a smaller sound stage than used during the pilot filming). Some episodes featured space aliens who wore costumes and carried props originally created for other Irwin Allen television and film productions. Prop sets were similarly reused. The prop computer, however, had an unusual degree of verisimilitude because it was an array of memory modules from the Air Force's recently decommissioned SAGE computer.
Continuity errors and errors in historical fact occurred in the series. In the premiere episode, "Rendezvous with Yesterday", Captain Smith of the Titanic is called Malcolm, when historically, his name was Edward. The names of the secondary officers are also fictitious, though Walter Lord's best-selling nonfiction book about the event, A Night to Remember, had been released nine years earlier. Tony states that he was born in 1938. A few episodes later in "The Day the Sky Fell in", he states he was seven when Pearl Harbor was attacked on 7 December 1941, which would make the year of his birth 1934, or possibly 1933, if later than 7 December. For comparison, Darren's birthdate is June 8, 1936, about midway between 1934 and 1938.
The music for the opening and closing credits heard in each episode of the series was composed by John Williams (credited, as in Lost in Space, as "Johnny Williams"). GNP Crescendo later released an album featuring Williams' work and the score composed by George Duning for the episode "The Death Merchant".
The series won an Emmy Award in 1967, for Individual Achievements in Cinematography. The award went to L. B. "Bill" Abbott, for his photographic special effects.

## Recurring elements

* A short "teaser" from the following week's episode was shown at the end of each episode as Doug and Tony arrived at their next destination, with one exception: episode three's ending teaser has a scene where Tony lands 10 years before 1968 in the desert, at the Time Tunnel complex. He tries to tell Doug that he works there, and he knows him. This was not to be seen in the following episode.
* The impressive introduction to the scale of the project (over 36,000 people and huge underground buildings) is never seen after the first episode except for two clips of the giant power generator flashing, and tunnel security running across a walkway. New matte paintings and models were created specifically for The Time Tunnel pilot episode.
* Most episodes involved the capture or detention of Doug, Tony, or both, their escape, their recapture, and their escape again, before their move to the next episode.
* Nearly all location shooting was filmed in and around Southern California. This caused scenes set in different parts of the country (or the world) to have the same general hilly landscape with arid-type trees and brush typical to the local region where filming occurred.
* The majority of episodes placed Tony and Doug in stories set in past historical contexts.
* Aliens and people from the future were similarly dressed, often in metallic silver clothing, like other Irwin Allen television series of the same era.
* Many episodes used stock footage from previous 20th Century-Fox and Irwin Allen productions. These shots ran the gamut from episodes on General Custer, to the sinking of the Titanic, and many other historical events.

## Episodes

While the episodes were first shown in 1966, the show's setting begins in 1968, two years into the then-future.

| U.S. Senator Leroy Clark (Gary Merrill) arrives in Arizona to evaluate Project Tic-Toc, which is researching time travel. Dr. Doug Phillips ushers Clark into a subterranean complex where he meets Lt. General Heywood Kirk. As chairman of the Senate oversight committee, Clark can either authorize or end the Time Tunnel funding. To prove time travel is possible, Dr. Tony Newman secretly enters the Tunnel and lands aboard the Titanic the day before it sinks. Doug later follows Tony into the past in an attempt to rescue him. Doug finds Tony and they enter the wireless room to send an SOS message, though the ship's crew apprehends them. When the ship strikes an iceberg as Tony and Doug predicted, the captain (Michael Rennie) orders the "abandon ship" procedure. Thrown off the ship by an explosion, Tony and Doug are successfully suspended in time by the Time Tunnel team. Senator Clark gives assurances that funding will continue as the time team attempt to rescue Tony and Doug. The DVD release included the series' original "pilot" that runs about 53 minutes rather than the standard 49 minutes. Deleted material was added to two subsequent episodes. |||||||

| 27 | "Merlin the Magician" | 544 | Harry Harris | William Welch | Cornwall, England | March 17, 1967 (1967-03-17) |
| Merlin the magician appears in Time Tunnel HQ and freezes the personnel. He then brings Tony and Doug out of their "time limbo" (between destinations) back to the Time Tunnel control room in suspended animation so that he can instruct them to do what he asks, though they may die in the effort. He then sends them to Cornwall in the year 544. There, they fight off a band of Vikings and encounter a young man named Arthur Pendragon whose father has been killed by the Viking raiders. Merlin appears and orders Tony and Doug to protect Arthur at all costs. Arthur declares he will make Doug and Tony his first knights, but they are transferred by the Tunnel. Note: The episode places Vikings in England approximately 250 years before the Viking Age and their first recorded appearance in the British Isles. Historians date the beginning of the Viking Age as 8 June 793, the day of the first Viking raid on the abbey on Lindisfarne. |||||||

| An alien time traveler from the future called OTT (acronym for "Official Time Traveler") (played by Del Monroe) appears in the Time Tunnel control room and abducts Dr. Ann MacGregor. Ray discovers a metal punched card presumably dropped by OTT that has a set of space-time coordinates. Kirk directs Ray to transfer Doug and Tony to those coordinates, which place them on a planet in the system of the star Canopus in the year 8433 A.D. They are in a futuristic complex run by a curator (Michael Ansara), who has begun to compile all the data of the history of the Earth by extracting the memories of all its historical figures. When the curator and the guards go dormant at night, Doug, Tony and Ann remain awake to retrieve the time-space converter and escape. They outwit and kill OTT, who by a power pack remains awake to patrol the alien complex; Ann sends herself back to the Time Tunnel control room with the converter by way of the alien time machine, and Doug and Tony are transferred away in the nick of time. This episode also makes use of Bernard Herrmann's music from the film The Day the Earth Stood Still. Note: This episode gives the distance to Canopus as 98 light years, a distance thought likely in 1967, whereas it is now known to be 310 ± 20 light years. |||||||
| 29 | "Raiders from Outer Space" | November 2, 1883 | Nathan Juran | Bob and Wanda Duncan | Near Khartoum, Sudan | March 31, 1967 (1967-03-31) |
| Tony and Doug arrive in the middle of the Siege of Khartoum between British and Arab forces in the Sudan. This chapter is loosely based on the campaign of General Gordon. In their efforts to hide from the battling armies, they encounter two aliens who take them prisoner. The alien leader (from Aristos) then contacts the Time Tunnel control center and tells them not to interfere. Unable to attack the aliens effectively with the resources at hand, Tony, Doug, and the British soldier fetch grenades and gunpowder from Khartoum. They attack the alien base, but have insufficient resources left to destroy it. However, just before the bomb explodes in the Time Tunnel control room, the Time Tunnel transfers the bomb to the alien base, destroying it a few minutes later. Note: The Battle of Khartoum was fought in 1884−1885. |||||||

| Tony and Doug arrive in a hotel cellar containing sophisticated equipment. When they get to the lobby of the hotel, the proprietor (played by Mabel Albertson) tells them that there is no cellar. When they attempt to show her, she immobilizes them. The Time Tunnel frees them from their immobilization by moving them. Doug and Tony flee and are pursued. A force field around the town prevents their escape, but two young people—Joan (Heather Young) and Pete (Gary Haynes)—soon encounter them. Tony and Doug find out that the townspeople have been immobilized and aliens are using the forms of the townspeople to appear as humans. The aliens are planning to transport all of the oxygen from Earth's atmosphere to their atmosphere-poor home planet of Andros. The aliens also start sucking oxygen out of the Time Tunnel headquarters, nearly asphyxiating the staff. Doug and Tony successfully destroy the alien control room, destroying their ability to remove Earth's oxygen, freeing the townspeople and saving Time Tunnel personnel. |||||||

## Cancellation

Although The Time Tunnel was scheduled on Fridays (often considered the "Friday night death slot" for TV programs), the ratings for the series were solid. ABC pointed to The Time Tunnel as one of the few successes in a disastrous schedule.
A series titled The Legend of Custer was lobbied to drop The Time Tunnel in favor of Custer. The network headquarters gave green light for Custer, and The Time Tunnel was cancelled.
The Legend of Custer was itself cancelled after airing 17 low-rated episodes, skewered by critics and performed worse than The Time Tunnel.

Also differing form the series, Senator Clark, here demands the end of Project Tic-Toc out of fear of grandfather paradox which could result in the erasure of the current timeline. THe action takes place during the Johnstown Flood of May 31, 1889, where the traveler's save Clark's grandmother, Julie Bowen., the Texas prairie near Adobe Walls, Texas, June 26, 1874, prior to the historic battle on June 27.

## Remakes

To date, three attempts have been made to resurrect the show. Two produced a pilot episode, and another got no further than a script.

### 2002 remake

In 2002, Fox showed interest in remaking this series. A pilot was produced by Twentieth Century Fox Television, Fox Television Studios, and Regency Television in association with Irwin Allen Properties. Kevin Burns and Jon Jashni were executive producers. Sheila Allen was credited as one of the producers. The series was not ordered by Fox so as to make room in its schedule for Joss Whedon's Firefly.
The pilot had a darker and more serious tone than the original 1966 series. Doug Phillips (David Conrad) is the main character, and the other is Toni Newman (Andrea Roth). The unaired pilot episode is available on DVD from Fox Home Entertainment on The Time Tunnel: Volume Two.
In this remake, the 2002 Time Tunnel is a Department of Energy research project into nuclear fusion, which produces nearly limitless energy. When the reactor was initiated (not shown in the episode), that caused an unintended "time storm" which uncontrollably changed history. The DOE was able to anchor one end of the storm by using the Tunnel like a lightning rod.
On their way into the tunnel complex, Flynn tells Doug Phillips, a former friend, that the latter has been recruited because he has a detailed knowledge of the Battle of Hürtgen Forest. The head of the Time Tunnel project likens their team to FEMA—they don't send a team back for a rain storm but they do for hurricanes. However, they can only go through time to where the other end of the storm is at the current moment, so they have a limited period to fix what is wrong and to be retrieved by the Time Tunnel.
The team (Doug, Toni, Flynn, J.D., and Wix) must travel to the Battle of Hürtgen Forest in 1944 Germany during World War II. They plan to retrieve a person moved there by the time storm from 1546. During the mission, Doug Phillips meets his grandfather, a soldier who will be killed in the battle. Doug knows this, but cannot tell his ancestor and save his life because it would change history. Toni Newman tells Doug she used to have three brothers and two sisters before the time storm accident but is now an only child. The time travelers learn the displaced person is a now-confused medieval monk who carries bubonic plague. When the team is almost captured, two members switch to German uniforms and pretend to be Colonel Klink and (Sergeant) Schultz, complete with fake documents. Everyone who came in contact with the monk is given an antibiotic injection and the time ripples stop, but Flynn has been fatally stabbed, so he reveals Phillips was a lonely single man before the time storm, but he now has a family. Flynn tells Phillips this information to give him an incentive to keep the timeline intact.

### 2006 remake

The SciFi Channel announced in 2005 to create a new pilot for its 2006/07 season. Allen's wife, Sheila, and two producers of the 2002 FOX remake (Kevin Burns and Jon Jashni) began work on the new pilot. John Turman (Hulk) wrote the script. The series never went beyond a pilot script.

## Parodies

A recurring sketch called Drunk In Time starred Alexei Sayle and Peter Capaldi as two men so inebriated that they weren't aware they were time travellers. Featuring a mock up of the original Project Tic-Toc set and animated Time Tunnel-style title sequence, the main characters are also called Doug and Tony. The six sketches featured in The All New Alexei Sayle Show in 1995.
