LONDON: Cameron Diaz is reportedly set to reunite with her Vanila Sky co-star Tom Cruise - in a new spy thriller. The pair teamed up to star in the 2001 movie alongside Penelope Cruz - and now they are set to go back to the big screen together again in a new untitled project with Walk The Line director James Mangold. A source tells British newspaper the Daily Express, "Cameron plays a woman on a blind date who ends up being embroiled in a dramatic adventure with Cruise, who portrays a top U.S. spy. With such an A-list duo involved, it's hoped this is going to be a big hit." The thriller is reportedly set to begin filming in October (09).
