Julia Roberts has joined the cast of Billy Ray's upcoming remake of the Argentinian thriller The Secret in Their Eyes. Gwyneth Paltrow and Chiwetel Ejiofor will also be starring.

The original movie won the Oscar for the best foreign-language film and follows Benjamin, a retired court employee that decides to write a book about an old rape/murder case that he believes wasn't properly solved. He becomes determined to find the real culprit and reopen the case, which turns out to be a complicated and thrilling quest that director Juan José Campanella depicts with a style that effortlessly juggles romance, comedy, suspense and political commentary.

Julia Roberts' role has not been revealed. She was last seen in August: Osage County, which earned her a Oscar nomination for best supporting actress. The film will re-unite the actress with Gwyneth Paltrow. The pair appeared in Hook starring Robin Williams back in 1991.

Billy Ray wrote and is directing the project. IM Global is fully financing the film, which starts shooting in October.
