From the moment he aided Charles Xavier (James McAvoy) and Wolverine (Hugh Jackman) in breaking Magneto (Michael Fassbender) out of the Pentagon in X-Men: Days of Future Past, Quicksilver (Evan Peters) cemented his status as a fan-favorite. That's why it was so disappointing when he did not accompany the other mutants on the rest of their adventure, staying behind in Washington, D.C. But Quicksilver's breakout status just meant that director Bryan Singer could bring him back for a larger role in the sequel, X-Men: Apocalypse.
Peters is indeed returning as the speedster for Fox's biggest X-Men film yet, teasing that he has a sequence that could top the memorable "Time in a Bottle" scene from Days of Future Past. Not only that, it sounds like Singer is keen on making Quicksilver a big part of the action, having him heavily factor into the "true birth of the X-Men" angle that Apocalypse is featuring.
When Screen Rant visited the Apocalypse set in July 2015, Peters was asked about his increased part. The actor revealed that he even gets a scene with the titular villain (played by Oscar Isaac), saying that he's part of the X-Men team that "go and try to take him down." Someone realized Quicksilver would be a valuable asset to the group, opening the door for the character to be a significant part of everything moving forward:
Screen Rant: Bryan was telling us that this movie is, among other things, about the formation of the X-Men. Is Quicksilver a significant part of that?
Evan Peters: Yeah. I would say that whatever happens down the line, that Quicksilver vanishes from the movies, I don’t know. At this point it is the beginning of him coming into the group and being a force that fights evil. It's pretty sweet... I still think he's good. He's not really … He hasn't gone to the dark side. I think he understands why Eric is the way that he is and does these things. I think he has a lot of sympathy for him and empathy and knows what he's going through and is trying to help him really. There's a way to go about doing this that’s not destroying people. You can do this the good way. Eric has so much anger and stuff built up inside him. I think he understands him. He's not on the dark side. Not yet anyway until something horrible happens, screw it all. We'll see.
The "Eric" Peters refers to is Eric Lensherr, the birth name of Magneto. In the comics, Magneto is the father of Quicksilver, an element that the movies have alluded to (Quicksilver's mom knew a man who could control metal), but never fully ran with. Peters spending so much time discussing the dynamic between Quicksilver and Magneto is interesting, since it suggests their relationship will be further explored in Apocalypse. Nobody is confirming that the two characters have familial ties, but the possibility is certainly there, which would set up rich arcs for both mutants. After losing the family he settled down with, how would Magneto react to learning he has a son?
Theorizing aside, the X-Men film team seems to be establishing Peters as one of the primary players for the franchise, which is a smart decision. McAvoy and Fassbender are rumored to remained involved post-Apocalypse, but Jennifer Lawrence is most likely finished with the series, and Jackman is stepping down as Wolverine following his 2017 solo vehicle. As Fox puts the spotlight on the younger versions of Cyclops (Tye Sheridan), Jean Gray (Sophie Turner), and Storm (Alexandra Shipp), they'll need some familiar faces to be the cornerstones of the team. Quicksilver would fit the bill, since he's already a fan-favorite moviegoers can't wait to see more of.
