20 Hugely Unexpected Roles In Upcoming Movies

The Role: Osbourne will apparently play himself in the rock concert scene that can be seen in the most recent trailer (where Patty has a ghost land on her shoulder).

Why It's Unexpected: Ozzy doesn't cameo in movies all that often, and Ghostbusters of all films seems like a pretty demented choice for the rocker.

Will It Work?: It depends on the nature of the gag: it's hard to imagine someone as bada** as Ozzy being 'fraid of a ghost, so hopefully the joke will be about him just shrugging off the paranormal invasion or perhaps even getting killed and turned into a ghost himself.

At least it should be delightfully surreal above else, so that's a "probably", then.
