Harrison Ford looks set to replace Bruce Willis in the latest installment of The Expendables action franchise.
Sylvester Stallone announced the casting change on Twitter.
It appears Stallone was more than happy with the casting change.
The Expendables 3 is due for release in August 2014 and will also star Arnold Schwarzenegger and Jason Statham.
Sylvester Stallone said that despite his Rambo image and new film Bullet to the Head, he is in favour of new national gun control legislation.
The American actor supported the 1994 "Brady bill" which included a now-expired ban on assault weapons and hopes the legislation can be reinstated.
He said: "I know people get (upset) and go, 'They're going to take away the assault weapon.' Who ... needs an assault weapon? Like really, unless you're carrying out an assault. You can't hunt with it. Who's going to attack your house, an army?"
"It's unbelievably horrible, what's happened. I think the biggest problem, seriously, is not so much guns. It's that every one of these people that have done these things in the past 30 years are friggin' crazy. Really crazy. And that's where we've dropped the ball, mental health," he added.
