We haven't heard anything about this film until now, but Twitchfilm has debuted a trailer for a Thai horror called The Coffin, which topped the country's box office this past weekend. You can see it below.
Directed by Ekachai Uekrongtham, the film is based on a Thai ritual that involves being put in a coffin to prolong life and ward off bad luck. The trailer suggests this doesn't always work, and can result in prolonged terror and outbreaks of creepy bugs and bleeding eyes. Well, we'd consider that grounds for a refund.
