Call yourself a film buff?

The Guardian has a fiendishly tricky film quiz up on its website. I got 25 out of 30, and I'm still not sure how since the only films I've seen at a cinema this year are Crank [brilliantly daft], Pirates: DMC [disappointing], Casino Royale [great, if a hair too long], Children of Men [wonderful], Night People [lovely] and Severance [gruesomely fun]. Have a go at the quiz, out-geek me if you can!
