'Deadpool 2' screenwriters explain how time travel will be used in the franchise moving forward

Warning: Spoilers below if you haven't seen "Deadpool 2."

• "Deadpool 2" screenwriters Rhett Reese and Paul Wernick believe the time-travel aspect will be used sparingly in the franchise.
• But it could potentially help to further the storylines of fringe characters who were introduced in the movie.

With Cable showing up in "Deadpool 2," it doesn't just mean the franchise is one step closer to having a real X-Force movie (as opposed to the one attempted in the sequel), but also that there are limitless possibilities due to the time-travel device he's brought along with him from the future.

Cable (played by Josh Brolin) is a soldier from the future who, thanks to time travel, returns to the present day to try and kill a young mutant named Russell (Julian Dennison) who killed his family. But things change when he comes across the Merc with a Mouth. By the end of the movie, Russell lives, Cable decides to not go back to the future, and Deadpool (Ryan Reynolds) borrows the device to time travel at the end of the movie and fix a few things - like save his girl Vanessa (Morena Baccarin) and kill Ryan Reynolds before he can make "Green Lantern."

And now with the time-travel option, screenwriters Rhett Reese and Paul Wernick are given endless possibilities for the franchise going forward. Are the mutants that Deadpool brought together to form X-Force in the movie really dead? And what else could Deadpool do with the device? Could he stop Charles Xavier from becoming a paraplegic? That one is probably not likely. However, there are a lot of places the franchise can go now.

Currently, it's a good way to calm down people who got a little overexcited about the X-Force gag in "Deadpool 2," like Deadpool comic creator Rob Liefeld.

"We told Rob, 'There's this time machine that allows us to go back and resurrect anybody,'" Reese said. "We told him just imagine that Shatterstar got resurrected at the end of the movie but we didn't show it."

The screenwriters told Business Insider that at the moment, time travel isn't planned to be a major part of the "Deadpool" movies going forward, but that doesn't mean it won't work for the other characters we saw, maybe only for a brief time, in the sequel.

"The way they are fooling with time, there's always ways to bring me back," Terry Crews, who plays Bedlam in "Deadpool 2," pointed out to Business Insider.

And hey, we know for sure X-Force member Peter is coming back!
