Keira Knightley has admitted she thinks about quitting the movie business because the pressure of fame is so intense. "The celebrity thing's completely crazy. I think I just have to move away or give it up altogether," the Pirates of the Caribbean actress told UK Elle mag, adding that she could "just do something else." Knightley revealed that she is fed up with being accused of being anorexic and stresses that she is just "naturally thin."
