Arnold Schwarzenegger, Sylvester Stallone unpack intense rivalry over body fat, machine guns and more

Arnold Schwarzenegger and Sylvester Stallone are still unsure who had the bigger career, comparing everything from body fat to machine guns and more. 

“We ended up kind of like, ‘Well, you killed 28 people in the movie; I killed 32,’” Schwarzenegger, 76, tells host Harvey Levin in Page Six’s exclusive preview of “TMZ Presents: Arnold & Sly: Rivals, Friends, Icons.” 

“I got to top that,” Stallone, 77, chimes in, describing his approach to navigating the pair’s longstanding rivalry. 

Schwarzenegger goes on to say that he and his equally muscled counterpart were competitive beyond the amount of characters they killed in their stream of action ‘80s action-thrillers. 

“It was now the body count and then it was kind of, like, ‘Well, what was your body fat? ‘I was down to seven percent,’ Sly said. And then I said, ‘I was down to 10 percent,’” the “Predator” star says of the “Rambo” icon. 

“So it became a competition with the body.”

Aside from their physiques, the former governor of California admits that he was even jealous of the weapons Stallone used on camera — and soon demanded machine guns that were just as impressive.

“And then he started using machine guns that were kind of, like, huge machine guns. I was running after him, he was not running after me,” Schwarzenegger says. “So I said, when we did ‘Predator’ … ‘I’ve got to have a bugger machine gun than Sly used in “Rambo.” So this is how it went.”

The clip concludes with the “Terminator” actor emphasizing that body count was perhaps the most important component of winning the game of Hollywood against Stallone. 

“He killed 80 people,” Schwarzenegger quips, “so I had to kill 87 people.” 

The duo’s dynamic eventually evolved into a strong, decades-long friendship, which is explored in Fox’s one-hour special.

“TMZ Presents: Arnold & Sly: Rivals, Friends, Icons” airs Tuesday at 8 p.m. ET on Fox and is available to stream the next day on Hulu.
