Recommend me some uber flicks

[Fusion]

I'm looking to bolster my DVD collection, and so am calling on the OcUK film fraternity to put forward a few suggestions of their favourite titles, particularly if they are lesser known gems, and especially if they are of the Sci-Fi, Thriller or 'mess with your head good and proper' categories.

I enjoy a wide variety of cinema though, so anything will be considered.

Thank you muchly

Cheers guys. I've got Memento, just haven't got round to watching it yet :/

Wish I could see it for the first time again.

See what you mean, throughly enjoyed it. Brilliantly structured, with a nice meaty denouement.
