Throw this in the cheap-publicity-enhances-already-legendary-satire bucket. Tom Cruise, taking actions that are sure to backfire, has thrown around his Hollywood weight in support of his creepy religion once again. To wit: Cruise threatened to pull all promotional support for MI:3 if Comedy Central continued with its plans to run a South Park episode with a satirical broadside against Scientology - both Paramount (the studio behind MI:3) and Comedy Central (the cable TV channel that brings you South Park) are owned by Viacom. Just say "GAH".
On the bright side, perhaps South Park is about to become relevant again.
