These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: American Graffiti
Dawson Casting: The only exception is for Mackenzie Phillips, who was 12 at the time of filming and played a 13 year old girl.
Magnum Opus: George Lucasthought this award-winner would be his. After this movie's success gave him official cred as a real movie producer, Star Wars was a fun "throw-away" project nobody (including him) expected to have more than a niche audience. The narration in original trailer for A New Hope called Lucas "the man who brought you American Graffiti".
Nightmare Fuel: For a nostalgic comedy, the film has a few genuinely creepy scenes.
Milner and Carol's visit to the auto graveyard.
Toad and Debbie's walk through the woods, where she tells him about the "goat killer" that's supposedly loose in the area.
Curt's mission to hook up the cable to the police cruiser's axle is accompanied by eerily-distorted train sounds.
