Ride/Coaster theming

What should the next theme ride/coaster be themed after?  We already know about Tomb Raider.  We already know of the idea of The Matrix too.  What other theming ideas are good for rides/coasters?

TOP 5
1. Alpengeist, 2. Magnum XL-200, 3. Superman: Ride of Steel (SFNE), 4. Volcano: The Blast Coaster, 5. Apollo's Chariot

I dont really think I would like htis one but if it is done right and the movie is good then they could do Harry Potter that is what somone was telling me about today.
