The Corridor (Lithuanian: Koridorius ) is a 1995 Lithuanian drama film directed by Šarūnas Bartas.
 It has a fragmentary narrative without dialogue and depicts several people in Vilnius.
 According to the director, the title symbolizes "the atmosphere of a corridor between yesterday and today, containing many doors".
The Honda J-VX was the first hybrid sports car concept to employ Honda's Integrated Motor Assist electric hybrid system and was initially unveiled at the Tokyo Motor Show in October, 1997.
 It achieved 70mpg (30km/l) and featured a 1.0 liter, 3 cylinder VTEC engine, supercapacitor electrical storage, an all-glass roof, airbag-like "air belts", used lightweight materials, and aerodynamic design.
 Eventually it would evolve into the Honda VV, a Pre-production prototype of the Honda Insight.
The Jusay Ancestral House is a historic house located in the Sampaloc neighborhood of Manila, in the Philippines.
 It was originally the home of the late couple Dr. Fernando Jusay and Rustica Palma which was eventually passed on to their late son Jose Jusay (born on June 24, 1944).
 The house was also called "The Door House" because it has so many doors inside.
 It was built in the early 1920s and its interiors as well as the exteriors are made of narra ("Pterocarpus indicus") wood.
 Galvanized iron sheet was used as roofing and the wall found outside the house is made of cement.
 According to the wife of the late Jose Jusay, Melody Urbano-Jusay, the two-storey house used to have five rooms, two bathrooms, dirty kitchen and a kitchen at the second floor and a basement with a secret passage which is now covered with cement due to road elevations that took place throughout the years.
The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine of the valve-in-block type designed by the Ford Motor Company and built by Ford and various licensees.
 During the engine's first decade of production, when overhead-valve engines were rare, it was usually known simply as the Ford V‑8, and the first car model in which it was installed, the Model 18, was (and still is) often called simply the "Ford V‑8", after its new engine.
 Although the V8 configuration was not new when the Ford V8 was introduced in 1932, the latter was a market first in the respect that it made an 8-cylinder affordable and a V engine affordable to the emerging mass market consumer for the first time.
 It was the first independently designed and built V8 engine produced by Ford for mass production, and it ranks as one of the company's most important developments.
 A fascination with ever-more-powerful engines was perhaps the most salient aspect of the American car and truck market for a half century, from 1923 until 1973.
 The Ford flathead V8 was perfectly in tune with the cultural moment of its introduction, leading the way into a future of which the Ford company was a principal architect.
 Thus it became a phenomenal success.
 The engine design, with various changes but no major ones, was installed in Ford passenger cars and trucks until 1953, making the engine's 21-year production run for the U.S. consumer market longer than the 19-year run of the Ford Model T engine for that market.
 The engine was on Ward's list of the 10 best engines of the 20th century.
 It was a staple of hot rodders in the 1950s, and it remains famous in the classic car hobbies even today, despite the huge variety of other popular V8s that followed.
The Honda Insight is a hybrid electric vehicle that was manufactured and marketed by Honda in its first generation as a three-door, two passenger hatchback (1999–2006) and in its second generation as a five-door, five passenger hatchback (2009–2014).
 The Insight was the first production vehicle to feature Honda's Integrated Motor Assist system.
 The first generation Insight is the most fuel efficient gasoline-powered car available in the U.S. without plug-in capability for the length of its production run.
 EPA estimates were 61 City/70 Highway/65 Combined.
 However, that was under the old EPA standards.
 Today's EPA standards reduced the estimates to 49 City/61 Highway/53 Combined.
 In December 2015, Toyota beat the Insight in City and Combined mileage by the new EPA estimate with the 2016 Toyota Prius Eco with EPA ratings of 58 City/53 Highway/56 Combined.
The Fabulous Clipjoint, first published in book form in 1947 (originally published under the title ``Dead Man's Indemnity`` in Mystery Book Magazine, April 1946), is the first full-length novel by writer Fredric Brown, who had honed his craft by publishing hundreds of short stories in the pulp magazines of the day.
 "The Fabulous Clipjoint" is also the first of seven detective novels featuring the nephew/uncle team of Ed and Am Hunter.
 The subsequent novels in the series are "The Dead Ringer", "The Bloody Moonlight", "Compliments of a Fiend", "Death Has Many Doors", "The Late Lamented", and "Mrs Murphy's Underpants".

The Castle is an MSX game released by ASCII Corporation in 1986.
 The game is set within a castle containing 100 rooms, most of which contain one or more puzzles.
 The object of the game is to navigate through the Castle to rescue the Princess.
 The player can push certain objects throughout the game to accomplish progress.
 In some rooms, the prince can only advance to the next room by aligning cement blocks, Honey Jars, Candle Cakes, and Elevator Controlling Block.
 Additionally, the player's progress is blocked by many doors requiring a key of the same color to unlock, and a key is removed from the player's inventory upon use.
 The prince must be standing on a platform next to the door to be able to unlock it, and cannot simply jump or fall and press against the door.
 The player can navigate the castle with the help of a map that can be obtained early in the game.
 The map will provide the player with a matrix of 10x10 rooms and will highlight the room in which the princess is located and the rooms that he had visited.
 The player must also avoid touching enemies like Knights, Bishops, Wizards, Fire Spirits, Attack Cats and Phantom Flowers.
Integrated Motor Assist (commonly abbreviated as IMA) is Honda's hybrid car technology, introduced in 1999 on the Insight.
 It is a specific implementation of a parallel hybrid.
 It uses an electric motor mounted between the internal combustion engine and transmission to act as a starter motor, engine balancer, and assist traction motor.
The Sunbeam 1000 HP "Mystery, or "The Slug"", is a land speed record-breaking car built by the Sunbeam car company of Wolverhampton that was powered by two aircraft engines.
 It was the first car to travel at over 200 mph.
 The car's last run was a demonstration circuit at Brooklands, running at slow speed on only one engine.
 It is today on display at the National Motor Museum, Beaulieu.
