I'm not going to rank them exactly and I've seen few of them more than once, but The Limey is probably my favorite,
followed by Sex, Lies and Videotape, The Underneath, and Traffic in uncertain order.
Probably followed by Out of Sight.
Probably followed by The Informant, Bubble, King of the Hill, Grey's Anatomy, and the Good German in uncertain order.
Then probably The Girlfriend Experience with Side Effects last.
You'd think that The Underneath would have gotten a decent DVD release by now, but it's only out in the same crappy 1999 release that is not anamorphic but does have a special feature about why widescreen is better than pan'n'scan.
