Arnold Schwarzenegger and Sylvester Stallone have costarred in three movies together in the past few years, the latest of which, a sort of awful action movie called "Escape Plan," opens today. But they weren't always so chummy. Stallone told David Letterman earlier this week (via The Telegraph), that during the '80s, at the peak of their tough guy rivalry (guyvalry?) in the eighties that they shared a "violent hatred" for each other. "Even our DNA hated each other," Stallone quipped.

"Have you ever had that ever?" Stallone asked the late night host, clearly forgetting about the rivalry that Letterman has shared with Jay Leno for decades (read "The Late Shift," Sly!) "Competition where you really had an arch enemy that kind of brings out the best in you. As Arnold would say, it really pushed you to accelerate." It got to the point where Stallone hated " "that [Schwarzenegger] was on the planet, basically."

Not that this competitive streak was all a bad thing. "After a while, I started to like this competition, this one-upmanship. He'd get a bigger gun. I'd shoot more people. He'd shoot more people." What might be the most fascinating aspect of this rivalry is when Stallone says that Schwarzenegger left him behind. Sly said: "But then, he went into science fiction, which kind of left me behind."

Of course, now that's all blood-stained water under the bridge. "Now we have this mutual respect, we're survivors, and now it's like, 'You know what? This guy is pretty special,'" he told Letterman. The duo will be seen in next year's "The Expendables 3" and, undoubtedly, team up to do other stuff.

No matter how old you get as an action icon, as long as you can still fire a gun, you'll be good.
