Hmmmm. I think Stallone would have done a better job in Kindergarten Cop and Running Man. In Cliffhanger, Stallone or Arnold would have worked. Now that I think about it, maybe Arnold was not the best choice for Terminator. Why would the Terminator be programmed with an accent? I think the Terminator should have had different voices for different situations, like the voice on your phone for map driving directions.
I’m starting to get irritated thinking about Arnold’s accent. He really was not an amazing actor. It was just his body, ruthless business sense, and personality/charm that propelled his success. I think other actors would have been better than him. And no, if we went back in time, and prevented Arnold from being an actor, it would not have caused a significant butterfly effect. The only ripple in time would have been that Planet Hollywood probably would not have existed.
