British actor Rupert Grint is worried his character will be killed off in the final part of author Jk Rowling's Harry Potter series - because he has become attached to the part. The red-headed star, who plays Potter's best pal Ron Weasley in the Harry Potter films, knows Rowling is hinting that a major character will be killed off in the final book. And he is afraid Weasley will be the one to die. Grint says, "I hope to do all seven and hopefully that'll happen."
