missing nose! I'm excited to see him play the role of young V, but a
bit bummed that they couldn't use the original Tom Riddle from COS.
Guess he looks too old now to play a teen?

Carol responds:
Christian Coulson was already twenty-three when he played the
sixteen-yer-old Tom in CoS. he nearly thirty now. He'd have been
perfect (with makeup) for the DADA interview, but apparently that
won't be included. He'd have been okay, too, for the Hepzibah murder
(another scrapped scene) since they almost always cast actors older
than the characters they play (Hero being an exception though ten
isn't that different from eleven.Uncle Vernon should be in his
forties, not much older than Snape et al., but the actor who plays him
is 61--and showing it, as of OoP.)

Anyway, here'd a link to Christian Coulson's IMDb page with a more
recent publicity photo (but I don't know how much more recent). While
you're there, you might check out Ralph Fiennes without Voldemort
makeup, for example this one from "Schindler's List."

Handsome but evil, right? More recent photos don't have the right
effect--not handsome enough and hair the wrong color. But I think I
see a family resemblance between him and little Hero (who seems
well-adjusted enough despite his name and early celebrity from what
little I've seen).

Carol, who agrees that Christian Coulson looked the part at the time
of CoS but doubts that he'd consent to playing a kid little more than
half his age now
