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. ↗
I mean it allowed me to do that which was fantastic because we really get to see the character mature and deal with some things that are, that I think as an audience member, really pull us in. ↗
You know those movies where the people in the audience are screaming, 'Don't go in that door!' because you know the killer is there? Well, it is the same thing with this debt. We know how this ends. ↗
