On Thursday’s episode of “The Tonight Show,” Sylvester Stallone told Jimmy Fallon about his long-standing rivalry with his "The Expendables 3" co-star Arnold Schwarzenegger.
“I’ve read that you guys actually hated each other for a while,” Fallon said.
“Well we were very competitive,” Stallone said. “Yeah, I think hate is a good word.”
“Did you ever hate someone so much that you’re like ‘I gotta go to the gym’?” Stallone said. “I really respect this guy, I think he’s brilliant, but I want to strangle him.”
Stallone explained that the two would try to top each other with action movies.
Fallon said, “You would do ‘Rambo’, and he—”
“–he would do Commando,” Stallone said.
