Well, "Jesus Christ" and "Superstar" aren't two words I'd think to put together, so that might be kind of interesting.

On the other hand, I've never been to Rome before, so it might be cool to see a movie that takes place there. (I'm guessing it does, anyway. For all I know, the title could be misleading.)

Might go with the first one, though, just because it's not really something I'd get the chance to watch back home.
