Grace looks set to join an impressive ensemble cast, which so far includes The Dark Knight Rises stars Anne Hathaway and Michael Caine alongside Matthew McConaughey (Mud), Jessica Chastain (Zero Dark Thirty), Casey Affleck (Gone Baby Gone), Ellen Burstyn (Requiem for a Dream), John Lithgow (Rise of the Planet of the Apes), Mackenzie Foy (The Conjuring), Timothee Chalamet (Homeland) and Bill Irwin (Monday Mornings).
Of course, we have absolutely no idea who any of these might be playing, nor indeed what the film is about, save for the fact that it will deal with theories of wormholes and time travel. Don't expect to find out much more until the film hits cinemas on November 7th, 2014.
