Unless G.I. Joe: Rise of the Cobra truly tanks, a sequel is all but inevitable.

With that in mind, producer Lorenzo di Bonaventura was asked which characters he'd like to see included in the next film.

"There's a ton of them actually... one of the hard things about tackling these things is that there's always the fan who says: 'Why didn't you pick Flint? Why did you pick Duke?' It goes on," he told IGN. "In general, what we've done with this, and what we did with Transformers, is you try to pick the most popular ones, and then if you're lucky enough to make another one, you use the next most popular.

"I think Flint's a cool character. And I've always liked the name Roadblock. I just think that's one of the greatest names ever. So somehow we've got to figure out how to get Roadblock in. I'm not sure I even like the character, but I love the name."
