8. Tom Felton
The Case For: Best known as Draco Malfoy in the Harry Potter series Felton has made some moves towards Hollywood, notably a supporting role in Rise Of The Planet Of The Apes. Felton was one of the child actors who came on well through the Harry Potter series, noticeably improving as the films went along. His career is moving steadily upward. Hes also blonde enough to make a passable Gosling.
The Case Against: Remember how awful Draco was to Ron on their first day of school? Or when he sent the snake after Harry in the Duelling club? How about the time he provoked Buckbeak, and his father did his best to see the poor Hippogriff executed? Plus he was part of the Inquisitorial squad, busting in on the DA meeting and forcing Dumbledore to flee Hogwarts! Thats an awful lot to forgive Tom. Theres no way you can be Gosling yet. Youve got to earn our trust back a bit at a time.
