Germany has banned the makers of Tom Cruise's new movie from filming at military sites in the country because the actor is a Scientologist.Scientologist: not good. 'Publicly professed': seems OK, given that this is what he is. Banning the making of the movie because of the beliefs and allegiance of one of the stars: not at all OK. Even if Scientology is a cult whose activities are 'directed against the free democratic order', it can hardly be said to constitute a significant threat to German democracy. And we're not even talking here about whether the organization's activities should be proscribed - only about whether a film can be made with the Scientologist actor's participation. What next? No showings of Rain Man and Collateral in Berlin or Leipzig?The German defence ministry said Cruise has "publicly professed to being a member of the Scientology cult".
