David Oyelowo joins Christopher Nolan's Interstellar

Despite claims that Wes Bentley would be the last piece of casting for Christopher Nolan's Interstellar , two more names have now been added to the team-sheet.

David Oyelowo and David Gyasi have both signed on to the science-fiction spectacular, scotching the idea that Bentley had filled the last remaining key role in the production.

Gyasi was most recently seen in Cloud Atlas , and had a background role as 'Skinny Prisoner' in The Dark Knight Rises , while Oyelowo has impressed in high-profile turns in Jack Reacher and Rise Of The Planet Of The Apes . Both actors appeared in Red Tails .

No specifics have been given as to who either man might be playing, but given the paucity of detail surrounding the film in general, that shouldn't come as much of a surprise.

What we do know is that the film will follow a team of space explorers who find themselves stumbling upon the possibility of time travel when encountering wormholes in the outer reaches of the galaxy.

Directed by Nolan and co-starring Anne Hathaway, Matthew McConaughey, Michael Caine and Casey Affleck, Interstellar will open in the UK on 23 August 2014.
