Fame is a tricky thing, and when that fame comes, it can have a profound impact on who you are as a person that is difficult to prepare for. For actor Robert Pattinson, his fame really kicked off when he was cast as Edward Cullen, one of the leads in Twilight. The Twilight movies, based on a series of incredibly popular young adult novels, became a smash hit at the box office, and made Robert Pattinson a household name with a long career ahead of him. But despite their commercial success, the experience of making the Twilight movies was not without its issues for the actor. Working on the franchise films caused Robert Pattinson to lose his sense of self, as he explained.
