Tom Cruise Scientology video leaked on YouTube

Over a soundtrack featuring the Mission Impossible theme tune, moist-eyed Cruise declares his dedication to his faith.

"Being a scientologist, you look at someone, and you know absolutely that you can help them," he enthuses.

"When you drive past an accident, it's not like anyone else; as you drive past, you know you have to do something about it, because you know you're the only one that can really help."

Well, it surely is car crash viewing.
