Maybe I should have known this already, but Will Smith is a scientologist (link mildly NSFW).
Nuts. I like his acting, and he seems funny and cool. But he's clearly a lunatic. Scientology is such tremendous garbage it makes the Moon Hoax look like brain surgery.
Of course, Tom Cruise is still a complete freaking nutbag:
Update: Sigh. Scientologists are two things (well, three, if you count pure evil): predictable, and litigious. The video was taken down. Oh well, it just had Tom Cruise rambling on and on about how scientology is wonderful, and can cure and do anything, except save a tanking career and make you not look foolish.
UPDATE II: Gawker.com has the video, and they are promising not to take it down. Go there to have your thetans inflated.
