The screen star - who is best known for his role as Edward Cullen in the vampire franchise - admitted that he has run out of steam at the right time as the final installment of the film is released later this year. He told ShortList: "Playing the same part for a while, you just run out of ideas. You feel kind of useless, you don`t know what to do anymore. "I`m not trying to get away from it. You`re screwing yourself, you`re saying you think your work is s**t if you try and get away from it." The 26-year-old reiterated: "And I never thought it was [s**t]. But I kind of got to the end of my inspiration." Robert appears in `The Twilight Saga: Breaking Dawn - Part 2` - in cinemas November 16 - alongside Kristen Stewart (Bella Swan) and Taylor Lautner (Jacob Black) and is looking forward to future projects. He added: "You get to the point where you`re like, `I don`t want to do a film for a teen audience anymore`."
