The opening scene from the movie 'Wayne's World' is one the most well known of all time. With the credits rolling Wayne Campbell slips the cassette into Garth's AMC Pacer built in tape deck and the rest is movie magic.
Mike Myers and the production team talk about the 'Bohemian Rhapsody' scene in an article at rollingstone.com. It ends up that Mike wouldn't do the movie unless the Queen tune was used.

Party On!
