"I don't know if I could ever really be cast in a heartthrob role apart from 'Twilight,' which I didn't really know was a heartthrob role. I really don't feel I am one"

In this quote, Robert Pattinson is revealing unpredictability about being cast in a heartthrob role outside of his famous role in the "Twilight" franchise. He admits that he was not conscious that his character in "Twilight" was thought about a sweetheart, and he does not think that he fits the typical meaning of a sweetheart. This could be due to his own personal insecurities or his desire to be seen as a serious star rather than simply a sweetheart. In general, Pattinson appears to be questioning his own appeal and whether he can be successful in roles that do not count on his sweetheart status.
