One of Deadpool’s best partners in the comics is Cable, the time-traveling, techno-organic virus, take no prisoners, leader of X-Force (who is also the son of Cyclops and a clone of Jean Grey). The two have a unique relationship and have gone on many adventures together throughout the comics. The stinger at the end of Deadpool was that Cable would be featured in the sequel and also have a significant role in the film. Although we still don’t know who will be playing Nathan Summers just yet, the screenwriters are now trying to give him a coherent origin story to translate to film.
Screenwriters Paul Wernick and Rhett Reese are trying to break Cable’s origin down as simple as they can. After all, they would have to go into the realm of cloning, Future timelines where Apocalypse is the ruler (and that movie didn’t go so well), Cable’s own evil clone and Mutant Liberation Front Leader, Stryfe, and a half-dozen other things from the comics that will just confuse the hell out of people. Part of getting the character down is getting the right actor as well, as Wernick says:
“It’s intimidating because we have to find his voice, and we don’t have an actor yet so we don’t know who we’re writing for. Most screenwriting happens without cast in place, but sequels it’s a little bit different and it’s likely that part will get cast, and we’ll get to continue writing it and honing it for that actor, which I think is a good thing. There’s been so many diverse people that have been brought up as possibilities for Cable, and who have not been brought up but we’re considering. And that, much like with Ryan [Reynolds], that decision will greatly impact his cadences, his rhythms. And we’ll certainly make him like he is in the comics, and we’ll certainly be faithful, but I do think that voice will inform us quite a bit.”
Wernick also comments that Cable needs to be simplified, and just have the “spirit” of the character, opposed to a true and blue origin story.
“So with Cable, he’s got such a convoluted past, and such a convoluted origin story that I think we’re going to try to leave that, not mysterious, but there are a lot of twists and turns, cloning and all this stuff where you go, “Oh my God. How do we get that across in a two-hour movie?” I think we’re going to distill him down to his essence. It will be authentic and faithful, but it’s not going to include the 18,000 details if you were going to read a Wikipedia page about Cable you’d roll your eyes.”
