I'll give this thread a bump with a film I hadn't even heard of until I decided to record and watch it on a whim:
November (2004)
It stars Courtney Cox and James Le Gros (the guy who kills Gary Busey and gets shot in the stomach in Point Break). Cox is a photographer who pretty much experiences three different scenarios involving a shooting at a convenience store. Having only seen it once, my brain is still recovering from the David Lynch-style butt-fucking courtesy of editor/director Greg Harrison. The screenplay is very inventive, but the way it was shot and edited really adds to the disorientation you the viewer feel as you're trying to piece together this intricate puzzle of a film (also, the sound design in the first "section" was unbelievable).
My Comcast synopsis described the film as an "involving mindbender" that "unraveled with Rashomon-like intrigue" and I think that is perfectly stated.
If you're in the mood for a good mystery or you just want to see an imaginative story told, I recommend being on the look out for November on IFC sometime in the future.
