It may be a little late, but Robert Pattinson is worried that his Twilight success will hamper his future acting endeavors. “Robert is frightened to death that for the rest of his career he will be known as Edward Cullen. No matter what other roles he plays, he will never be able to shake off Edward’s fangs and it terrifies him,” a friend of the British star tells Popeater. “Of course, Rob loves the money that the role has made him, but he is only 24. To think your career has already peaked before you hit 25 is not a good thing.”
