Steve Carell has denied rumours he will leave hit U.S. show The Office to concentrate on his burgeoning movie career. The former postman starred in the first three series of the Emmy Award-winning comedy and has since landed roles in big budget films including 2007's Evan Almighty and this year's Get Smart. The funnyman had been dogged by rumours he is set to leave the programme to take on more high profile lead roles. But he insists that he is definitely going to stick with The Office for the foreseeable future. He says, "All of the main cast are signed for three more (seasons). Beyond that, I have no idea."
