* AwardSnub: Averted when it was nominated for five Oscars - Picture, Director, Original Screenplay, Editing, and Best Supporting Actress for Candy Clark - but played straight when it lost all five. Granted, it was the same year ''Film/TheSting'' and ''Film/TheExorcist'' came out.
* CommonKnowledge: The film is often cited as being the inspiration for ''Series/HappyDays'', when in fact it was more or less the other way around. ''Grafitti'' was inspired by an episode of ''Love, American Style'' starring Ron Howard, and then its success inspired Garry Marshall to expand that episode into a whole show.
* HilariousInHindsight:
** Steve's remark about Laurie's BigBrotherAttraction, when you realize this film is made by the same guy responsible for the ''Franchise/StarWars'' movies, [[Film/TheEmpireStrikesBack one of which]] is infamous for a passionate kiss between Luke and Leia [[Film/ReturnOfTheJedi before they find out they're siblings.]]
** Ron Howard would later direct a ''Star Wars'' movie, but only after some serious drama between the studio and the original directors that Lucas himself would be proud of.
* OneSceneWonder:
** Suzanne Somers as the Blonde in the T-Bird. All she does is mouth "I love you" at the camera and fans have been wondering about her character ever since.
** Although his God-like voice is present throughout the movie as background chatter, Wolfman Jack's actual appearance at the end - offering Popsicles and wisdom - counts. It was even more so at the time, as his appearance was the first time his legions of fans got to see what he looked like after two decades of his radio show.
* RetroactiveRecognition: For a big chunk of the cast.
* SeinfeldIsUnfunny:
** Fifties nostalgia, now old hat, was still [[NostalgiaFilter a pretty novel subject]] for a film in 1973.
** The habit of movies looking back a decade or two with a nostalgic melancholy in general. ''Film/CooleyHigh'', ''Film/DazedAndConfused'', ''Film/BoogieNights'', a lot of ComingOfAge movies... it all started with this movie.
* {{Sequelitis}}: The original ''American Graffiti'' is regarded as a classic and one of Creator/GeorgeLucas' 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.
