Topher Grace is in negotiations to join the growing cast of director Christopher Nolan's Interstellar for Warner Bros.

No details about the actor's character were given, but he joins a cast that already includes Matthew McConaughey, Anne Hathaway, Jessica Chastain, Michael Caine, Bill Irwin, Casey Affleck, Mackenzie Foy, and John Lithgow.

Christopher Nolan is directing from a screenplay he co-wrote with his brother Jonathan Nolan, which is based on the scientific theories of Kip S. Thorne, who believes that wormholes exist and can be used for time travel. The director is also producing alongside Emma Thomas and Lynda Obst, with shooting scheduled to begin this fall.
