* DawsonCasting: The only exception is for Mackenzie Phillips, who was 12 at the time of filming and played a 13 year old girl.
* MagnumOpus: Creator/GeorgeLucas ''thought'' this award-winner would be his. After this movie's success gave him official cred as a real movie producer, ''Franchise/StarWars'' was a fun "throw-away" project nobody (including him) expected to have more than a niche audience. The narration in original trailer for ''Film/ANewHope'' called Lucas "the man who brought to you ''American Graffiti''".
* SeinfeldIsUnfunny: Fifties nostalgia, now old hat, was still a pretty novel subject for a film in 1973.
* {{Sequelitis}}: The original ''American Graffiti'' is regarded as a classic and one of George Lucas's best movies outside of the ''Star Wars'' franchise. ''More American Graffiti''? Not so much.
* TearJerker: Finding out the fates of John Milner and Terry the Toad (unless you've seen the sequel) in the epilogue.
