Sets where everybody hated/hates (https://tvtropes.org/pmwiki/pmwiki.php/TroubledProduction/LiveActionTV) the show and each other.

my cousin worked on the show COMUNNITY and said the cast was pretty nasty (especially Chevy Chase who he says was a real s.o.b.) He also worked on THAT 70S SHOW and says some of that cast was the same way.
