<p><br /> Will Ferrell stars opposite Brad Pitt in Dreamwork's latest animation Megamind, where he voices the title character, an unsuccessful master villain.<br /> </p><p><br /> Will Ferrell says he joined the cast as the story was unique: "It was just more of a creative choice that felt exciting and a great cast and a great original premise for the movie.<br /> </p><p><br /> "A great kind of take for the superhero movie that hasn't been told before."<br /> </p><p><br /> Ben Stiller, who worked as executive producer on the film, believes this is not your average tale of a hero and villain.<br /> </p><p><br /> "Megamind is going through this mid-life crisis where he's having this existential dilemma of what his life is about.<br /> </p><p><br /> "Once he gets rid of his main rival all of a sudden he has nothing to do in life. And so that idea of the villain being the protagonist was a really fun idea for a film," he said.<br /> </p><p><br /> Megamind is released in UK cinemas on 3 December.<br /> </p>
