Television heartthrob Matthew Fox has moved on from the mysterious island of Lost to In a Forest Dark and Deep on the London stage. The actor is making his West End debut in the world premiere Neil LaBute play, and we’ve got a look at the show’s official trailer. Fox stars as Bobby, who spends a dark and stormy night helping his sister Betty (Olivia Williams) clear out her forest cottage. But nothing is as it seems in this cabin, and the tale of sibling rivalry quickly becomes a savage psychological thriller. The dark comedy runs March 3-June 4 at the West End’s Vaudeville Theatre; for a stateside look at this eerie Forest, check out the video below!
