George Clooney and Matt Damon stunned staff at a gym in Cambridge, England on Sunday (02Jun13) after booking the basketball court for a work out.

The Hollywood pals, who are in the U.K. to shoot World War Ii movie The Monuments Men, turned up at the Kelsey Kerridge Fitness Centre to face off on the court, but had to be asked to wrap up their game after their time slot was over.

Manager Liane Shadrack says, "They shot a few hoops but I did feel a bit bad throwing them out after their hour was up."

Damon had previously stopped by the fitness centre solo on Saturday night (01Jun13).
