Tom Cruise & Cameron Diaz Talk 'Knight & Day' Set Stunts

Tom Cruise and Cameron Diaz reignite their chemistry on the big screen for the first time since 2001's 'Vanilla Sky,' and only our own Mary Hart is with them on the top-secret Boston set of their new action-comedy, 'Knight & Day,' where they've been doing a lot of their own daring stunts!

"She's done a 180 in a car -- ཽ GTO the other night," says Tom. "She does it. She's a very good athlete. Very coordinated and excellent."

A globetrotting adventure featuring big action, big laughs and big stars, 'Knight & Day' finds Tom and Cameron as a fugitive couple on the run – creating an opportunity for plenty of explosive moments along the way, including a sequence in which Tom is hanging on top of a speeding car that Cameron's driving!
