This might be why the lead actress couldn't make it to comic con.
Oh, now which interview was it, if I can be bothered I'll find it again though I think it is linked in one of the many links in this thread - in the interview she said she previously could only get cast in roles that were bad-ass-types that weren't very deep. It goes further, though this bit might from another interview further back - where she said she couldn't get cast for any acting roles in her home country, so that's why she went to the US.
