I haven't seen anything from Thai filmmaker Wisit Sasanatieng, but I love both Apichatpong Weerasethakul and Pen-Ek-Ratanaruang. (Believe me, I spelled both on my own.) Last Life in the Universe was one of the best films I saw last year, and I was also impressed with Ratanaruang's sex-comedy 6ixtynin9 quite a bit.
