Basically it's matching the photos from the movie to a name which you have to type. I got 26, but 2 of them I can't place, 1 I'm sure I know but don't have a clue, and 1 I have no idea about.
Anyhow - 26/30 is your score to beat. Good luck.
edit - 27 now! Finally got the one with all the helicopters. Too many movies feature scenes like that.
