The cast of the upcoming The Super Mario Bros. Movie, Chris Pratt, Keegan-Michael Key, Charlie Day, and Jack Black all appeared on The Kelly Clarkson show yesterday, though one of them was dressed…a little peculiar.
Jack Black was in full costume of his character Bowser, and the fellas revealed that it was the result of a little "prank" everyone played on Jack.
The Super Mario Bros. Movie is scheduled to hit theatres April 5!
