Okay, it's not actually a real movie, just a spoof trailer that came out a little while ago. (I guess Christopher Lloyd had a free weekend and a good sense of humor?) Depp's champion of a performance as the slightly-kinda-psychotic Wonka is unchallenged. But this trailer by itself is better than several "real" movies I've seen over the years, honestly.
Also check out the "movie" website and a fun making-of video. It must've been odd filming a horror trailer where most of the shots are either dialog-free or screaming. :D
