Is Tom Cruise crazy?

I imagine most people have seen this Tom Cruise Scientology video, or at least parts of it. People are tripping over themselves to talk about how nutty he is. And he's pretty nutty, to be sure. But put his nuttiness aside for a minute. His demeanor in the video isn't really that crazy. He looks intense, at times, and full of conviction. What makes most people see it as creepy and wacky is that he's feeling this way about Scientology, which is unscientific mumbo jumbo.

Now contrast this with this Reader's Digest interview with Denzel Washington. Now the interview is general, not specific to religion, but religion does permeate it. He's very spiritual, he reads the Bible all the time, puts God first etc... Now is Denzel any less nutty than Tom? Can you not picture him in a church video talking about his relationship with God with the same intensity Cruise does with Scientology?

The main difference I see is that Tom's cult doesn't have quite as many followers as Denzel's cult. Are Thetans and audits any nuttier than angels or transubstantiation?
