In the trailer bin, the full-length preview for Tropic Thunder, with Ben Stiller, Jack Black, Steve Coogan, Nick Nolte, and, uh, Robert Downey Jr. in blackface. (Downey’s got a pretty high degree of difficulty here to not crash and burn, obviously, but my guess is he’ll probably be less off-putting than Fred Armisen’s cringeworthy Obama.) And, while it’s probably straight-to-video, I like the admittedly gimmicky premise: the trailer for Rosencrantz & Guildenstern are Undead, i.e. Hamlet with vampires.
