Colin Morgan as Merlin + Jack Frost – Celebrity Doppelgangers
Maybe it's the hair, maybe it's the brown cloak, maybe it's the ears or maybe it's the magical powers, but the CGI'ed Jack Frost in 'Rise of the Guardians' looks an awful lot like Colin Morgan, who plays the eponymous Merlin on the BBC show.
In the now officially wrapped series 'Merlin,' Morgan plays a young version of Merlin, the fictional sorcerer from the King Arthur mythos, who must hide his powers against the megalomaniac and all around idiot king of Camelot, Uther Pendragon. He must also hide his latent homosexual tendencies from his bestie Arthur Pendragon.
Or at least that's what we see when we watch it.
Jack Frost (voiced by the drool-worthy Chris Pine) was a once human boy who later became the magical Jack Frost of Christmas specials, white hair and all. Or possibly, Colin Morgan fell into an alternate dimension while filming and became trapped in a world where he was a CGI character. Headcanon accepted.
