MUMBAI: Tom Cruise and Cameron Diaz are now before the cameras on the action comedy KNIGHT & DAY. The Twentieth Century Fox / New Regency co-production began principal photography under the working title Untitled Wichita Project.

James Mangold directs KNIGHT & DAY from a screenplay he co-wrote with Scott Frank. The writing credit is not final. The film is produced by Cathy Konrad, Steve Pink and Todd Garner. Executive producers are Joe Roth, E. Bennett Walsh and Arnon Milchan.

In Knight & Day, Cruise and Diaz have a glamorous and sometimes deadly adventure, where nothing and no one – even the now fugitive couple – are what they seem. Amid shifting alliances and unexpected betrayals, they race across the globe, with their survival ultimately hinging on the battle of truth vs. trust. Knight & Day is now shooting in Massachusetts, and will also film on other locations around the world, including Spain, Austria and the tropics.

Also starring are Peter Sarsgaard as a federal agent relentlessly pursuing the couple; Viola Davis as a CIA director trying to decipher the true purpose of their high-wire activities; Paul Dano as an eccentric genius behind a revolutionary technology; and Olivier Martinez as a ruthless arms manufacturer. Co-starring are Maggie Grace and Marc Blucas.

Twentieth Century Fox will release Knight & Day on Fourth of July weekend (2 July), 2010.
