For anyone who's got an Alamo Drafthouse nearby, they're doing an entire John Carpenter film retrospective this summer. In addition to The Thing, they're pretty much showing one of his movies a week all summer long. Halloween '78, Prince of Darkness, They Live, Christine, Escape from NY, Starman, etc.
EDIT: You might want to pass. There's a lot of talk online that the Fathom screenings yesterday were awful. The sound quality being awful, that they fucked up the aspect ratio to fit the screen (cropping the sides and the bottom) and that the picture was soft/barely DVD quality. Some of that might just be weirdo purists being hyper critical but there's even tweets from movie people saying don't bother (Mick Garris, for one).
