Steve Martin 'No pranks on movie set'

Steve Martin insists the set of his new movie The Big Year was all work and very little play.
The actor says despite a cast including himself, Jack Black and Owen Wilson, there were no pranks.
“It wasn’t really a prank filled set,” he says.
“When I hear ‘prank filled set,’ I think, I’m so glad I’m not on that movie! You know what we should have done. We should have hired a writer to come up with pranks that we could have said we played! To me it’s nose to the grindstone.
“You know, to get the work done. I’m not a prankster. But on April Fools Day, I go around and change people’s calendars. To April second!”
