The Coffin

The Coffin is a 2008 horror film starring Karen Mok and Ananda Everingham. It's supposed to be good luck, according to Thai tradition, to spend a night in a coffin. News to me.

DVD Talk says, "In all ways, this is an engaging film. Highly recommended." From Horrorphilia:

Wrap up
Overall there is enough good stuff that happens that I can recommend it to Asian horror fans, but I think the average Jo Blo horror guy won’t like it much. With a little bit more emphasis on the dramatic side and less horror, I think this movie could have been really special. As it stands now it’s just pretty good.
