Devon Murray
Devon Murray was introduced to the big screen back in 2001 in the first installment of the Harry Potter series. Murray played Seamus Finnigan, a small boy with a knack for messing up spells and laughing only at inappropriate times.
While his character begins as an outspoken mess, constantly blowing things up accidentally, his skills for pyrotechnics returns in the series' final film installment, when he blows up a bridge saving his friends from the Death Eater army. Considering skills alone, Murray's character has gone from zero to hero (and he's not too bad to look at either!).
