Take my vote for Timecrimes. Another little movie that I liked very much is "Frequently Asked Question About Time Travels", and the two "Hot Tub Time Machine".

Take my vote for Timecrimes. Another little movie that I liked very much is "Frequently Asked Question About Time Travels", and the two "Hot Tub Time Machine". OK, the second was really weak, but the leads are hilariously funny... Last one, I promise, "Time Lapse".
