Newie: Dark Knight for sure, though it'll be hard the first time Heath Ledger comes on screen.
Oldie: Gatica, just to demonstrate what a good script, a (at the time) hot chick, and minimal sfx can accomplish.
Obscurie: Brotherhood of the Wolf. It's French, but still a bad-*** horror flick, with one of the coolest weapons on film. I found it in Hollywood Movies, so it may not be all that hard to nab.
