When you get the kind of numbers that the spy action thriller Safe House grossed, which was near $202 million worldwide, it’s probably a safe bet that a studio would want to move forward with a follow-up. And that’s what Universal is doing. They have already hired the film’s original writer David Guggenheim to write a draft for what will either be a sequel or a prequel.

And why is it unclear whether it will be a sequel or a prequel? Well there are some potential spoilers that explain why, so if you haven’t seen the movie already, don’t hit the jump.
