In an upcoming joint TV interview titled 'TMZ Presents: Arnold & Sly: Rivals, Friends, Icons', the actors said they are still unsure who has the bigger career, reports femalefirst.co.uk.

A preview of the chat shows Schwarzenegger sitting with Stallone, saying, "We said something like, 'Well, you killed 28 people in the movie;' I hit 32''

Stallone said: "I got over him."

Schwarzenegger then said: "He killed 80 people, so I had to kill 87 people."

The 'Rambo' and 'Rocky' star said: "Now it was body count and then it was relative, like, 'Well, what was your body fat?' "I was down seven percent."

To which Schwarzenegger said: "And then I said, 'I was down 10 percent.' So it became a competition with the body."

The 'Terminator' star and former California governor said he is jealous of the weapons Stallone uses on camera, from his 'Rambo knife' to the sub-machine gun used in the 'Rambo' franchise .

He admitted that he soon demanded automatic guns that were just as large.

Schwarzenegger continued: “And then they started using machine guns that were like giant machine guns. I was running after him, he was not running after me. So I said, when we did 'Predator'... 'I'd rather have a bugger machine GU than the sly machine used in 'Rambo.' So that's how it went."

The two have enjoyed a decades-long friendship since the 1980s when they were arch rivals.
