Right now, it's definitely Prometheus. I know that The Dark Knight Rises is going to be great, but Prometheus is one of my most anticipated movies ever. I grew up watching Alien and Predator films and playing all the video games, or even collecting action figures and models when I was younger. A prequel will just be icing on the cake to me.
I really hope that Ridley Scott doesn't end up disappointing me, although he never really has. Maybe I'm setting my bar a little too high for Prometheus.
BQ: Oh wow, I don't even know. There are so many great scenes. I think I would narrow it down to either the scene where the Joker is interrogated, the hospital bombing scene, or the Joker's introduction to the mob. Heath Ledger was just too good in The Dark Knight. Every scene was memorable.
BQ2: Again, they both had a ton of fantastic scenes. The first scene to come to mind from Aliens is the part where the signals from the aliens are on top of the group, so Nicks lifts up a panel in the ceiling only to reveal a **** ton of them. That scene was pretty intense.
BQ3: Happy birthday to him. He's definitely one of the classiest actors to ever live. My favorite films with him involved are the Prestige and Batman Begins. If you're talking starring roles, then the Quiet American is probably my favorite.
