Wes Bentley joins Christopher Nolan's Interstellar

Wes Bentley is the latest big name actor to join Christopher Nolan's decidedly er, stellar, ensemble for upcoming sci-fi Interstellar , and is thought to be the final piece in the primary casting jigsaw.

According to Heat Vision , Bentley will be taking on "a meaty supporting role", although specific details have been kept predictably vague by Nolan's camp.

The report also claims that the addition of Bentley will bring the film's casting process to a close, with Bentley filling "the final vacant slot in the film's lineup".

Upon signing on the dotted line, Bentley will join an impressive lineup including Matthew McConaughey, Anne Hathaway, Jessica Chastain, Casey Affleck, Michael Caine and Topher Grace.

As mentioned previously, plot details are few and far between, but we do know that the film will follow a group of space explorers, discovering wormholes and time travel in the outer reaches of the galaxy.

Interstellar will open in the UK on 7 November 2014.
