I was watching Terminator again and it made me think, Arnold would have SUCKED as Kyle Reese. Michael Biehn brought a softness and a vulnerability to the character that Arnold could never bring.
Arnold would make a good solider but the tender moments with sarah would have sucked
the movie is so intense at times BECAUSE of how weak Kyle becomes at some parts of the movie, either from being injured or just for being less strong than the Terminator.
Arnold could never portray that weakness, Arnold (Even injured) could not portray the level of vulnerability Michael did.
Arnold was perfect for the Terminator the same way Michael was perfect for Kyle Reese. a perfect combination. Im pretty happy Arnold didn't take the soldier role. glad he talked Cameron to making him terminator. it was perfect.
