I bet you've seen just about every English-language film released this year! Same with 2009.
I only went 8 times last year. I saw State Of Play, The Proposal, Toy Story 3D, Zombieland, Michael Jackson's This Is It, Avatar, Four Christmases (special re-release for seniors 60+ but I got in) and Sherlock Holmes.
I also saw The Hurt Locker this year, but that was originally released in '09 so I don't know if it counts or not.
I tried to get in to see The Taking Of Pelham 123 and Couples Retreat last year but I was ritually humiliated by the cinema staff both times.
