Here's Tom Cruise getting to grips with a feisty Cameron Diaz on the set of their new movie.

The former Vanilla Sky co-stars have reunited for Wichita, about a couple whose blind date becomes complicated when Tom's character reveals himself to be an FBI agent.

Tom and Cameron struggled and glared at each other during takes but the stern looks melted into laughter when the cameras stopped rolling.

Tom and Cameron have been hanging out off-set too, attending a U2 gig together at the weeken.

“Cameron Diaz was dancing the entire time, turning around to laugh and smile at Tom and Katie (Holmes)," said an onlooker.

"And when Bono asked the crowd to take out their cellphones to create light, even Cameron took out her BlackBerry.”

Wichita is currently filming in Boston.
