Last Action Hero is a 1993 American fantasy action comedy film directed and produced by John McTiernan and co-written by Shane Black and David Arnott. It is a satire of the action genre and associated clichés, containing several parodies of action films in the form of films within the film. The film stars Arnold Schwarzenegger as Jack Slater, a Los Angeles police detective within the Jack Slater action film franchise, while Austin O'Brien co-stars as Danny Madigan, a boy magically transported into the Slater universe, and Charles Dance as Mr. Benedict, a ruthless assassin from the Slater universe who escapes to the real world. Schwarzenegger also served as the film's executive producer and plays himself as the actor portraying Jack Slater. The film also marked Art Carney and Tina Turner's last feature film before their deaths in 2003 and 2023, respectively.

Last Action Hero failed to meet the studio's expectations at the box office, and was both a critical and commercial disappointment. Since its release Last Action Hero gained a cult following, with some noting it as underrated in Schwarzenegger's catalogue.
