* SugarWiki/AwesomeMusic: This spawned not just one but two hit soundtrack albums, repackaging several hits from the '60s and making them popular for a new generation (though Music/{{The Rolling Stones|Band}}' "You Can't Always Get What You Want", which is critical to the funeral scene, isn't included on either album, presumably due to licensing issues). However, thanks to this movie, [[OnceOriginalNowCommon soundtracks like that became a trend]], and became decried for merely being nostalgia tools.
* HilariousInHindsight:
** As discussed on ''Podcast/EightiesAllOver'', Creator/JeffGoldblum plays the one principal character whom ''no one'' wants to sleep with, but in the decades since this film gave his career a leg up (prior to ''Film/JurassicPark'', this and ''Film/TheFly1986'' were the cornerstones of his reputation) he's become MrFanservice to several generations of fangirls and boys through subsequent roles, a sort of sweet {{Revenge}}.
** When Sam admits to playing video games to relax, Meg says it's moronic. Fast forward 20 or 30 years, and almost '''everyone''' does it.
* SpiritualSuccessor: While there was a (short-lived) direct TV adaptation called ''Hometown'', it could be argued that ''Series/{{thirtysomething}}'' is a better example.
** The film itself could be seen as one of these to Creator/JohnSayles' 1980 independent film ''Film/ReturnOfTheSecaucusSeven'', which similarly depicts a group of former Sixties radicals reuniting in the same house over a weekend. Kasdan has gone on record as saying he hadn't seen the movie before writing the script.
** ''Film/AboutAlex'' is perhaps the most transparent one in history.
