The 25-year-old star, who gained millions of fans with his portrayal of Edward Cullen in the franchise, said he is glad to be leaving the teen tales behind.
"Playing the same part for a while, you just run out of ideas. I'm not trying to get away from it. You're saying you think your work is bad if you try and get away from it. And I never thought it was bad.
"But I kind of got to the end of my inspiration. You get to the point where you're like, I don't want to do a film for a teen audience anymore," he said. The final movie, "The Twilight Saga: Breaking Dawn Part II", is scheduled for release in November this year.
