James Nesbitt has said he hasn't lost his enthusiasm for TV despite years of success.
The actor is heading back into the operating theatre for a new series of ITV1 drama Monroe.
James, who plays brain surgeon Gabriel Monroe in the drama, said: "The minute I get jaded is the minute someone should push me off the acting cliff."
He said of his latest TV role: ""I've loved it because it's something I never knew anything about really.
"And I've got the odd bit of medical literature at home which I can tap into if I'm learning lines for the next day."
The former Cold Feet star is set to star in Peter Jackson's Lord Of The Rings prequels on the big screen.
He said that filming the Hobbit movies was "exciting", calling it "a great epic year in a wonderful epic country."
Monroe starts on ITV1 on Monday, October 1.
