I thought I'd share this CNN piece on Troma from a few years ago. As of right now, Hollywood is remaking Toxic Avenger (spoiler: it's going to suck) and Lloyd Kaufman is directing the fourth installment of Class of Nuke'em High. Be careful where you open that link; there are less pornographic trailers for actual pornos.
Kaufman has said for years that Troma's in financial trouble. According to the grapevine, it's in more trouble than ever before. It seems Troma's response to their difficulties is uploading their library of films to the net to watch for free. I guess the idea is to generate revenue from the ads that display during the movies. You can watch their movies here.
My two all-time favorites are Tromeo & Juliet and the more recent Poultrygeist: Night of the Chicken Dead, a chicken-zombie musical that skewers the fast food industry.
