Young British actor Harry Eden, no question. Check out his performance in the ITV drama "Real Men", or "Pure".. he is astonishingly accomplished. Now 18, he's playing the young Joe Scott, in Flashbacks of a Fool, which stars Daniel "Bond" Craig.
He is also probably one of the nicest kiRAB in the business. I met him a couple of years ago, and was seriously impressed by his level-headedness, politeness and maturity. A real pleasure to chat to, and certainly a pleasure to watch onscreen.. he tackles tough subjects like drug addiction and child abuse with such ease and confidence he is going to be a force to be reckoned with as an adult actor.
Up until I saw him, I would have said Haley Joel Osment, but this guy seriously kicks him out of the window!
