I don't look at scripts in terms of commerciality. I just look at the part, the people involved.
I took group lessons at a rink near my home. We first had to learn how to stand up on the ice wearing skates. Eventually we learned to move forward, but soon found out that it was not that easy to stop! So that was our next important lesson.
And I have been able to establish this sort of decent reputation as being a decent character actor.
