Almost ten years after they first worked together on Vanilla Sky, Tom Cruise and Cameron Diaz have reunited for the film Knight and Day.

And after around a decade working apart, they still get on like a house on fire.

"She's so talented, such a warm, fun person to work with, and I think that's reflected in the piece," said Tom at the London premiere of the action rom-com.

"I think people are going to have a really good time. We're not promising we're changing the world or anything, it's just a good time," said Cameron, 37.

The film is directed by James Mangold, whose previous credits include 3:10 to Yuma and Walk The Line.

Knight and Day opens in the UK on August 6.
