Just about every producer in Hollywood.
Not from what I’ve heard.
Stars gotta be insured in case they fall down, go boom in the middle of filming (very expensive when that happens). Out-of-control substance abusers can’t be insured, therefore no producer will hire them for fear of having their shooting schedule upended. Hollywood can forgive just about anything, up to and including pedophilia (re: Victor Salva, Roman Polanski) but that’s where they draw the line.
