Hmm, I can see that. He even sort of fits as an adult of Sean Biggerstaff.
Only thing with casting Sean is his age. [I could look up how old he is, but it's more fun to do the maths]. The main HP cast are now, 18ish? and he started off 2/3 years older. He's got to be at least 20 by now. Not sure how old Fox is supposed to be.

It'd be good to get an all Scottish cast, I always like it when they have all British cast for British stories, so an all Scottish cast for a Scottish story would take it even further into coolness.

I dunno; the PM, James Bond, Dr Who... they'll be letting you vote next.
