Wait, what happened about what?
If you mean why Vince is pissed at Scientology it's because they invested in a movie he made (Underground Comedy Movie) and once they found out how not funny it was they held a "trial" and declared him an incompetent buffoon. Then they told everybody who was a Scientologist not to work with him (and Hollywood's full of them) and he says that in turn cost him a ton of money.
So now he's suing them.
