"We started out really hating each other... Even our DNA hated each other! We were just really, really competitive... Now we have this mutual respect, we're survivors, and now it's like, 'You know what? This guy is pretty special." Sylvester Stallone on his newfound friendship with fellow action hardman Arnold Schwarzenegger. The pair star together in new movie Escape Plan after previously teaming up for Stallone's The Expendables franchise.
