Shallow Grave
the insanity and paranoia captured from the trauma and greed of the film's characters is so perfect. i don't think any film has captured the sense of tension that this one has and it does it so well because of the fun and believable chemistry the 3 friends have in the first half of the film. the use of sexuality is so minor in this film but is so incredibly powerful. Juliet is able to use her womanhood to manipulate anyone she sees fit, even David, the most paranoid and careful character, gets seduced by her and allows her to very nearly sink her claws into assured victory. the way her sensuality is used is so perfect. the way she casually strolls out of the bathroom with her top off in front of Alex is not only used as a gag but also to begin to show how these 3 friends will use sexuality to fuel the actions of the others throughout the film.
perfect cinema. top 5 of all time. no film does it like this one does. young Ewan McGregor is illegal amounts of hot also.
