I've had such an embarassing crush on that guy since he was on "Home and Away", an Aussie soap import to the UK. His acting wasn't bad (But since it was Kenneth Branagh who finally cast him, he may have as yet untapped reserves of acting skill), but ye gods he was just so damned pretty!
I agree with someone whose noted he might have been a more obvious choice for Captain America (Look, if you buggers can make Kevin sodding Costner Robin Hood, then a Brit Director can cast an Australian as one of YOUR folk heroes)
