Kenji Wu and Pitchanart Sakhakorn star, and a quick look at the film's website reveals at least a couple more familiar faces: Somchai Sakdikul, who will hopefully bring his patented form of comic relief, and Ampon Rattanawong, who most memorably served as the monkey shaman in Buppha Rahtree.
Here is the synopsis,Via 24 Frames per Second:
An unsuccessful man in Taipei commits suicide, only to wake up in the body of a coma victim in Bangkok. His new life is almost perfect - he now has a stable job, a healthy body and a beautiful wife, but as the two souls fight for control of the body they start developing supernatural powers over life and death itself, leaving havoc in their wake.
Skyfilms, by the way, is also a distributor. They have been bringing Thai films to Taiwan, including Bangkok Love Story, Sick Nurses, 13 Beloved and Dynamite Warrior.
