Ray Stevenson has expressed interest in sequels, hinting Barracuda as a possible villain. At the 2008 San Diego Comic-Con, when asked if he signed on for more Punisher movies, he said, "If I had my wish, it's going to run and run. It's up to the fan base. If this works, we get to do it all again."[60] Commenting on the film's villains, Stevenson stated: “We dispatched a few, but there are some other great ones,” he laughed. “Some of the great stories that are in [the Punisher comics], there is one about the Slavers — the prostitution rings, and bringing women over from Europe. There is also Barracuda, who is almost as mean and ornery as Frank. Some are more real, or more tangible than others, while some of them are larger-than-life like Jigsaw, but there are plenty [of stories to tell]. What I love is the depth that [writer] Garth Ennis gets to; he doesn’t do broad brush strokes, he really gets in there. These villains have a real motivation, a real determination that must be stopped, and you get to play off of it. That should be fun.”
