Wayne's World (1992)

Mike Myers and Dana Carvey turned a Saturday Night Live sketch about two metalheads with a public-access show into the highest-grossing movie ever made from an SNL sketch. It still holds up because it is so cheerfully silly: fourth-wall breaks, fake endings and a cast that clearly enjoyed itself. The car scene set to "Bohemian Rhapsody" is the famous one, and it sent the Queen song to number two in the United States all over again. If you only know the catchphrases, the movie around them is sharper than you would expect.
