Castmates Play Cruel Trick On Damon

Actor Matt Damon was left red-faced before the first matinee performance of his London play when castmates teased him with a cruel prank.

The "Good Will Hunting" star was sent out on stage for the first afternoon performance of "This Is Our Youth" at the British capital's Garrick Theatre, in which Damon performs alone for the first five minutes.

But the actor was stunned to walk out at 3pm and find the auditorium empty.

Unsure of what to do, and convinced that nobody had turned up to see him and co-stars Casey Affleck and Summer Phoenix, Matt carried on with the play - until he heard fits of uncontrolled laughter from the wings and realised he was the victim of practical joke.

His castmates had neglected to tall him the matinee had been put back until 4pm.
