Well, I confess - I really liked number one. Its my guilty-pleasure movie ...
anyhoo Cage said about n.2

"All they have to do is call, and I would love to see that happen. That would be fun."
Same goes with Johnson
"I'd love to do another one," he said. "But that's really up to Sony now. I'd like to see what Mephisto has in store for Johnny down the road. Safe to say, that things are going to get worse for Johnny before they get better!"
I think that would be another dumb movie ... but hey, why not?, lol
