An interactive film is a video game or other interactive media that has characteristics of a cinematic film. In the video game industry, the term refers to a movie game, a video game that presents its gameplay in a cinematic, scripted manner, often through the use of full-motion video of either animated or live-action footage. In the film industry, the term "interactive film" refers to interactive cinema, a film where one or more viewers can interact with the film and influence the events that unfold in the film. Design This genre came about with the invention of laserdiscs and laserdisc players, the first nonlinear or random access video play devices. The fact that a laserdisc player could jump to and play any chapter instantaneously (rather than proceed in a linear path from start to finish like videotape) meant that games with branching plotlines could be constructed from out-of-order video chapters, in much the same way as Choose Your Own Adventure books are constructed from out-of-order pages. Thus, interactive movies were animated or filmed with real actors like movies (or in some later cases, rendered with 3D models) and followed a main storyline. Alternative scenes were filmed to be triggered after wrong (or alternate allowable) actions of the player (such as 'Game Over' scenes). A popular example of a commercial interactive movie was the 1983 arcade game Dragon's Lair, featuring an animated full motion video (FMV) by ex-Disney animator Don Bluth, where the player controlled some of the moves of the main character. When in danger, the player was to decide which move, action, or combination to choose. If they chose the wrong move, they would see a 'lose a life' scene, until they found the correct one which would allow them to see the rest of the story. There was only one possible successful storyline in Dragon's Lair; the only activity the user had was to choose or guess the move the designers intended them to make. Despite the lack of choice, Dragon's Lair was very popular. The hardware for these games consisted of a laserdisc player linked to a processor configured with interface software that assigned a jump-to-chapter function to each of the controller buttons at each decision point. Much as a Choose Your Own Adventure book might say "If you turn left, go to page 7. If you turn right, go to page 8", the controller for Dragon's
