Let's see, checked out his MySpace page and apparently this 25-year-old was on Canadian idol, so I guess Canadians can give the rest of us an indication if he's a good actor, etc.
However, this bit of potential casting does bear out the initial news release about "mostly young... explorers" and Kate Hewlett's blog note that they were casting young. I suspect the cast, with the exception of the Colonel character (I think the odds are 50/50 if he lives or dies) and Robert Carlyle, will in their early/mid-twenties...
