A guy named Tyler Mane. He never worked for Vince. He was in WCW in 1989 as Woman's bodyguard for a short time, then disappeared to Puerto Rico and Japan before coming back in 1993 as Big Sky. His second run was just as short as the first one and he retired from wrestling in 1996 to pursue acting. His highest-profile role was Sabretooth in 2000's X-Men, a role that was originally meant for Kevin Nash but he couldn't take because of WCW conflicts.
He pretty much sucked as a wrestler.
He plays Michael Meyers in the Rob Zombie Halloween movies.
