Their adaptation of Susan Hill's novel The Woman in Black will be arriving in 3D. When it's expect to arrive is anyone's guess, but we do know a few solids at this point. Jane Goldman (Kick-Ass, the upcoming X-Men: First Class) is adapting the screenplay about a lawyer who begins glimpsing a woman dressed all in black whilst he spends time in a clients house to sort through their estate for director James Watkins (Eden Lake). The film already has distribution in a number of markets overseas and up North, though it looks like Hammer and Alliance Films are currently looking for a US distributor at the Cannes Film Market (hence this 3D announcement).
I really could care less about seeing this in 3D, but I do remain excited for the film based solely on Watkins' involvement. Eden Lake was one of the most chilling horror movies of 2008 for me - there are character deaths in that movie that still get to me - so I'm sold on Watkins no matter what dimension his films are presented in.
