Chris Hemsworth is like Christopher Reeve in that he can do two things: he can wear a big red cape without a shred of self-consciousness. But he's also funny as hell and he's so sweet. So with all the fish-out-of-water stuff he's so funny. So he does almost two jobs in a way.
I was in two episodes playing Christopher Reeve's character's emissary. They wanted to have my character announce Dr Swan's death which I thought was exploitative.
Christopher Reeve did such an amazing job that to give him some kind of accent or more bravado would have been wrong. Audiences wouldn't have responded to that either.
