I always take kind of a zen view of casting and I really don't remember people who passed. I kind of turn it over to the universe and figure, 'Wow, I guess that wasn't meant to be.' It doesn't sit with me.
I also know that in the second movie, the sequel, Eric made some huge advances with the robot suit. That just made it even better. You put the suit on and moved your arms then the robot's arms would move in sync with yours.
