Island of Terror is a 1966 British horror film released by Planet Film Productions.
 The film was released in the US by Universal Studios on a double bill with "The Projected Man" (1967).
 The idea for the film came when Richard Gordon read the Gerry Fernback screenplay "The Night the Silicates Came".
 He partnered with Tom Blakey of Planet Films to produce this movie.
Melchor Palmeiro (born 1923) represented Argentina at the 1948 Summer Olympics in London.
 He was entered in the 1500 m, where he finished fifth in his heat recording a time of 4:01.6 and failed to advance.
 His personal best in the 1500m was 3:57.8 when he came first at the 1947 South American Championships.
 He also came second at the Championships in 1943 and again in 1949.
Lebanon hosted the 3rd Mediterranean Games in Camille Chamoun sports city in Beirut.
 The event took place from 11 to 23 October 1959.
 11 nations were represented by a total of 792 athletes, all males, competing in 17 sports of 106 events.
 France came first: its 66 athletes won 69 medals (26 gold), while the host country, Lebanon, with the most athletes (180), came 8th with 30 medals (only 3 golds).
 The United Arab Republic, participating for the first and only time as Egypt and Syria, came second (the UAR in the 1963 games included only Egypt).
Thomas Lee "Tommy" Kirk (born December 10, 1941) is an American former actor and later a businessman.
 He is best known for his performances in a number of highly popular movies made by Walt Disney Studios such as "Old Yeller", "The Shaggy Dog", "The Swiss Family Robinson" and "The Misadventures of Merlin Jones", as well as beach party movies of the mid 1960s.
Underdog is a 2007 American family superhero comedy film based on the 1960s cartoon series of the same name.
 Directed by Frederik Du Chau and written by Joe Piscatella, Adam Rifkin, and Craig A. Williams, the film stars Jim Belushi, Peter Dinklage, John Slattery, and Patrick Warburton with the voice talents of Jason Lee, Amy Adams, and Brad Garrett.
 Unlike the TV series, the Underdog character is portrayed as a regular dog rather than an anthropomorphic one.
 Underdog, voiced by Jason Lee, was played by a lemon beagle named Leo sporting a red sweater and a blue cape.
 The film grossed $65.3 million worldwide.
The 1952 Isle of Man Tourist Trophy was the start of Bob McIntyre's association with the Isle of Man, when he came second in the Junior Clubman TT that year.
 Irishman Reg Armstrong won his first Senior TT event as well as coming in second in the Junior TT race on a Norton.
 Armstrong, as a Norton works rider, was back-up to Geoff Duke who came first in the Junior race.
The Monkey's Uncle is a 1965 Walt Disney production starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello (Who was a member of the mouseketeers from The Mickey Mouse Club) as his girlfriend, Jennifer.
 The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" (a legal arrangement resulting from an experiment to raise Stanley as a human); Stanley otherwise has little relevance to the plot.
 Jones invents a man-powered airplane and a sleep-learning system.
 The film is a sequel to the 1964 film "The Misadventures of Merlin Jones."
The Misadventures of Merlin Jones is a 1964 Walt Disney production starring Tommy Kirk and Annette Funicello.
 Kirk plays a college student who experiments with mind-reading and hypnotism, leading to run-ins with a local judge.
 Funicello plays his girlfriend (and sings the film's title song written by brothers Robert and Richard Sherman).
Anatoly Lutikov (5 February 1933 in Leningrad – 15 October 1989 in Tiraspol) was a Russian chess player.
 He was awarded the International Master title in 1967 and the Grandmaster title in 1974.
 He won the Moldovan championship six times (1963, 1964, 1965, 1966, 1968, 1977).
 He came third in the USSR Chess Championship 1968/69, finished second behind Boris Spassky at Wijk aan Zee 1967, was first at Dubna 1971, tied for first at Leipzig 1973 and came first at Albena 1976.
The Roper steam velocipede was a steam-powered velocipede built by inventor Sylvester H. Roper of Roxbury, Boston, Massachusetts, United States sometime from 1867–1869.
 It is one of three machines which have been called the first motorcycle, along with the Michaux-Perreaux steam velocipede, also dated 1867–1869, and the 1885 Daimler "Reitwagen".
 Historians disagree over whether the Roper or the Michaux-Perreaux came first.
 Though the "Reitwagen" came many years later than the two steam cycles, it is often, perhaps most often, known as the "first motorcycle" because there is doubt by some experts that a steam cycle meets the definition of a motorcycle.
