Twitch has some glimpses of promotional images from Cannes for three Thai films - Chocolate, Tabunfire and 13.
You'll have to go there to look at them, and read the reader comments while you're there.
Their description of Chocolate is a hell of a lot cooler than it sounded when the movie was first described in another post about Tony Jaa directing Ong Bak 2. Then, it was described as a children's movie. But now, it's about about kick-ass kid in a martial-arts revenge flick that they are comparing to Danny the Dog.
Tabunfire stars Dan Chupong, from Born to Fight (and, supposedly the upcoming Nonzee Nimibutr film, Queens of Pattani), and Panna Rittikrai, the martial-arts choreographer on Ong Bak, Tom Yum Goong, The Bodyguard, director of Born to Fight and director of dozens of Thai B-movie action movies. It marks his return to the screen for the first time in quite some time. It involves buffalo rustlers, black magic and the menstrual blood of a virgin.
13 is a thriller starring Krissada Terrence of Bangkok Loco, and looks to be quite a bit different than that bit of candy-colored mayhem.
