what was the first movie to have a post credit scene
Post-credits scene One of the earliest appearances of a post-credits scene in a modern mainstream film was in The Muppet Movie in 1979, and use of such scenes gained popularity throughout the 1980s at the end of comedy films. In 1980, Airplane! ended with a callback to an abandoned taxicab passenger who was not a primary character, and who had not been shown since the film's first scene. The Muppet Movie also began a trend of using such scenes to break the fourth wall, even when much of the rest of the film had kept it intact. The scenes were often used as a form of metafiction, with characters showing an awareness that they were at the end of a film, and sometimes telling the audience directly to leave the theatre. Films using this technique include Ferris Bueller's Day Off (in which the title character frequently broke the fourth wall during the film) and the musical remake of The Producers. The post-credits scene in the latter film also includes a cameo appearance by Producers creator Mel Brooks.
Closing credits The use of closing credits in film to list complete production crew and cast was not firmly established in American film until the 1970s. Before this decade, most movies were released with no closing credits at all. Films generally had opening credits only, which consisted of just major cast and crew, although sometimes the names of the cast and the characters they played would be shown at the end, as in The Wizard of Oz, Mary Poppins, Oliver! and the 1964 Fail Safe. Two of the first major films to contain extensive closing credits – but almost no opening credits – were the blockbusters Around the World in 80 Days (1956) and West Side Story (1961). West Side Story showed only the title at the beginning of the film, and Around the World in 80 Days, like many films today, had no opening credits at all.
