Jessica Chastain in talks for Christopher Nolan's Interstellar, Michael Caine joins the cast

Now that he's finished up with the Dark Knight trilogy, Christopher Nolan is gearing up to go into space for his next effort, the sci-fi epic Interstellar, and according to Deadline Jessica Chastain (Zero Dark Thirty) is in talks about joining the film as the "third lead". Matthew McConaughey (Magic Mike) was the first name to sign on for the film, followed by Oscar winner Anne Hathaway (Les Miserables), who will reunite with Nolan following her turn as Catwoman in The Dark Knight Rises.

Jessica Chastain enjoyed her big breakthrough in 2011, which saw her appearing in Take Shelter, Coriolanus, The Debt, The Tree of Life and Texas Killing Fields, along with her Oscar nominated supporting turn in The Help. She followed this up last year with a Best Actress nod for Zero Dark Thirty and has several films on her upcoming slate, including the relationship dramas The Disappearance of Eleanor Rigby: His and Hers, period drama Miss Julie and Guillermo del Toro's Victorian ghost story Crimson Peak.

Update: Well, it was only a matter of time, and sure enough Michael Caine has been now announced as the latest addition to the cast of Interstellar, reuniting with Nolan for the sixth time after Batman Begins, The Prestige, The Dark Knight, Inception and The Dark Knight Rises. No word yet on Caine's charatcer, nor anything much about the film at all, save that involves a journey into the far reaches of space and will provide "an exploration of physicist Kip Thorne's theories of gravity fields, wormholes and several hypotheses that Albert Einstein was never able to prove."

Insterstellar is set to arrive on November 7th, 2014.
