Zack Sharf Digital News Director Arnold Schwarzenegger admitted on a new episode of “The Graham Norton Show” (via NME) that his rivalry with Sylvester Stallone “got out of control” during the 1980s and ’90s. The two actors emerged as action movie icons around the same time that Schwarzenegger released “The Terminator” and Stallone starred in “Rambo.” “We were movie rivals, but we took the competitiveness to the extreme – we each had to have the best body, we had to kill more people in our films and we had to have the biggest guns,” Schwarzenegger said. “It got out of control and we tried to derail each other.” “Then when we both invested in Planet Hollywood, we started flying around the world together to promote it and we became fantastic friends,” he continued.
