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.
Montage (filmmaking) From the 1930s to the 1950s, montage sequences often combined numerous short shots with special optical effects (fades, dissolves, split screens, double and triple exposures) dance and music. They were usually assembled by someone other than the director or the editor of the movie.
