A new BBC adaptation of Daphne DuMaurier's "Jamaica Inn" is being made. The author must be floating in her grave with relief; by all accounts, she really disliked the comic version made by Alfred Hitchcock.
New BBC adaptation of Jamaica Inn is filiming.
Edited in October 2016 to add that I've finally seen the adaptation and it's quite good, fairly faithful to the book's tone and the characters' psychological struggles. However, it was filmed far from Cornwall and to me the scenery just didn't have the same impact. Maybe I spent too much time in Cornwall, wandering in Daphne's writerly footsteps.
