Lair or Cliff Hanger was programmed to go to the next chapter in the successful story if a player activated the correct control, or to go to the death chapter if they activated the wrong one. Because laserdisc players of the day were not robust enough to handle the wear and tear of constant arcade use, they required frequent replacement. The laserdiscs that contained the footage were ordinary laserdiscs with nothing special about them save for the order of their chapters and, if removed from the arcade console, would play their video on standard, non-interactive laserdisc players. Later advances in technology allowed interactive movies to overlay multiple fields of FMV, called "vites", in much the same way as polygonal models and sprites are overlaid on top of backgrounds in traditional video game graphics. Origins The earliest rudimentary examples of mechanical interactive cinematic games date back to the early 20th century, with "cinematic shooting gallery" games in the United Kingdom. They were similar to shooting gallery carnival games, except that players shot at a cinema screen displaying film footage of targets. They showed footage of targets, and when a player shot the screen at the right time, it would trigger a mechanism that temporarily pauses the film and registers a point. The first successful example of such a game was Life Targets, released in the UK in 1912. Cinematic shooting gallery games enjoyed short-lived popularity in several parts of Britain during the 1910s, and often had safari animals as targets, with footage recorded from British imperial colonies. Cinematic shooting gallery games declined some time after the 1910s. Capitol Projector's 1954 arcade electro-mechanical game machine Auto Test was a driving test simulation that used a film reel video projector to display pre-recorded driving video footage, awarding the player points for making correct decisions as the footage is played. It was not intended to be cinematic or a racing game, but was a driving simulation designed for educational purposes. An early example of interactive cinema was the 1967 film Kinoautomat , which was written and directed by Radúz Činčera. This movie was first screened at Expo '67 in Montreal. This film was produced before the invention of the laserdisc or similar technology, so a live moderator appeared on stage at certain points to ask the audience to choose between two scenes. The chosen scene would play following an audience vote. An early example
