Warning: these videos contain very NSFW moments!
Apparently people fainted in the theater during Bite's premiere, which isn't too surprising: it's about a girl who gets bitten by a strange insect and starts grotesquely turning into a giant bug herself, and the movie keeps trying to top its own grossness throughout its runtime.
Altered StatesOut of context, this scene is absolutely insane. Hell, within the context of the movie it's insane, too. But I'll just let you watch the video and decide for yourself what you're seeing.
DemonsYou know those dreams where your teeth fall out? And then get replaced by sharp demon teeth? And also the rest of you has totally turned into a demon as well? No?? Must just be the dreams I have after watching Demons.

SocietyUgh. Oh God, gross. So gross. Wait, maybe this part is... OH #$%@ING GROSS!! THIS WHOLE SCENE IS HORRIFICALLY DISGUSTING!! And for these reasons, I think you'll very much enjoy this clip from Society.

"Are you a dog person or a cat person?"

An American Werewolf In LondonAs great as the werewolf transformation is in The Howling, this is the gold standard. It's so good that the rest of An American Werewolf In London could have been unremarkable and we'd still be talking about it, but in fact it is quite remarkably good as a whole.
long-form transformation in movie history? Quite possibly. Jeff Goldblum plays a nerdy scientist in this landmark role that would pave the way for him to star in Jurassic Park as a nerdy scientist and Independence Day as, um, a nerdy scientist. The Fly revels in the joys of slowly turning into a fly, including puking on donuts and puking on people's legs.
