Robert Pattinson

No, “vampire” is not an accent (ask Colin Farrell), but most of us know Robert Pattinson from his role as Edward, the shimmery lily-white vampire in the four “Twilight” movies (the fourth one comes out this Thanksgiving). Edward speaks in an American accent that suggests some kind of European aristocratic background. He’s also faked an American accent in “Remember Me” and “Water for Elephants.” In August he’ll be going all Yank-speak one again, this time for David Cronenberg’s “Cosmopolis.”
