Friends know the right people in London in regards to film premieres

I met him very very briefly at Batman Begins premiere... Actually he wasn't going to come over but then my pen fell on the floor and suddenly he came running to pick it up for me. Gentleman lol
Inception was luckier, I met him one on one literally (well, there were two girls with me who didn't seem to care about anyone besides DiCaprio so I had Nolan all for myself), it was a little too overwhelming so I sounded like an ass.
I found out today I can fly over for TDKR premiere so hopefully my friends can help me out again. If not then I will either try red carpet, though that kinda sucks.. or just try Gary Oldman, if he's there this time, just to pass on things to Chris lol
What do you guys have in mind? As it's birthday month.. I was thinking about a big book with letters or whatever. Something he'd appreciate.
