Last Action Hero

Last Action Hero is a 1993 American comic fantasyaction film directed and produced by John McTiernan. It is a satire of the action genre and associated clichs, containing several parodies of action films in the form of films within the film.

Danny Madigan is a teenage boy living in a crimeridden area of New York City with his widowed mother Irene. To escape from his harsh reality, Danny often skips school to watch movies at the rundown Pandora movie theater, owned and managed by Dannys friend Nick. Nick receives the film reels for Jack Slater IV, the latest in one of Dannys favorite film series starring Arnold Schwarzenegger as the titular Los Angeles police detective and violent action hero, and offers to show it to Danny at a private screening just before the world premiere. To mark the occasion, Nick tears up a special ticket he received from Harry Houdini years ago, giving one half of the stub to Danny as a keepsake.As the film starts, Danny is unaware that the stub glows with magic. When a lit stick of dynamite exits the film during a car chase scene and lands in the theater, Danny instinctively ducks for cover. When he comes to, he finds that he is now in the film, riding along with Slater who is in disbelief as how Danny arrived. At the LAPD headquarters, Danny tries to explain how this is all a film and explaining who the bad guys are, but Slater does not accept this. Despite this, Slaters supervisor, Lt. Dekker, assigns Danny to work with Slater given his apparent knowledge of the villain. Danny leads Slater to the home of mob boss Tony Vivaldi which he saw in the opening of the film. Vivaldi denies any wrongdoing and Slater is unable to arrest him despite Dannys assurance of his crime. As they depart, Vivaldis assassin, Mr. Benedict, overhears Danny talking about the ticket stub, and discretely follows the two. That night, Benedict orders an attack on Slaters home while he is introducing Danny to his daughter, Whitney. While Slater and Whitney fend off the attackers, Benedict is able to steal the ticket stub from Danny. ........
