Murder/mystery/detective film recommendations needed

[IceBus]

I've been on a bit of a murder/mystery thriller kick lately and I'm struggling to find other movies that fit the bill.

If people could recommend things along the same lines as Zodiac, Se7en, Usual Suspects etc. that'd be excellent. I've seen a lot of the mainstream detective stuff like LA Confidential, Memento etc. but I'm hoping there's a few I've missed.

Thanks for any recommendations!

Unfortunately I've seen those (Gosford Park, David Gale and The Departed). Keep them coming - at the very least this'll be good for recommendations for other people lol.

Wow guys, thanks for all the recommendations so far. I rented out Primal Fear last night and it certainly didn't disappoint Brilliant twisting/turning storyline and amazing acting from Ed Norton, every time I see him I'm amazed he's not more critically acclaimed.

In terms of some of the other recommendations... Mr Brooks I saw in the cinema and absolutely love - phenomenal performances from Costner and William Hurt and again a brilliantly disguised storyline. The Prestige, Collateral and are also great. I'm surprised I've seen so many of the other recommendations, obviously a sign of a misspent youth!

Chinatown, Third Man, Unthinkable, Presumed Innocent, Reversal of Fortune and Frantic (where's my wife?) all added to the list
