Mel Gibson was RoboCop 1987 Mel Gibson even tho Peter Weller was perfect.
Somehow I feel like he'd be wrong for the role. A little too larger than life for Murphy.
Imagine Dolph Lundgren
LOL! It's funny you mention him. I just watched Aqua Man last night and it was weird seeing him with red hair and a red beard.
How about Arnold as RoboCop and Peter Weller as Terminator. Lol
