Here's what he told Collider:
"Yes I have heard about a sequel and I’d be the first to say yes to a phone call from Sly. I mean, we spoke about it as soon as the movie started to do really well and he says, you know, it would be great to do this again, and if there’s anyone who can do a good sequel it’s Sly Stallone! He’s done a fair amount. Yeah, we had a good time. It’s something I’d like to repeat."
Filming for
"The Expendables 2" is hopefully set to begin later this year - although no official release date is yet in place!
