Just looking at casts and directors i'd go for:
Australia
The Changeling
Curious case of Benjamin Button
Dark Knight (obviously)
The Fighter
Forbidden Kingdom (Jet Li and Jackie Chan together
)
Indiana Jones
James Bond (but i reckon this'll slip into 2009)
Jumper
Rambo
Star Trek?!? (Didnt have a clue this was being made and with JJ Abrahms at the helm it should be pretty darn weird)
Valkyrie
So a nice bag there, but theres alot of films in that list i think would be better going straight to video (X-Files 2?!)
