While the Marvel Studios movies and Marvel Studios Netflix series both fall under the same umbrella and can legally crossover with one another, that doesn't necessarily mean they will.
Take it from Daredevil himself, Charlie Cox. The actor recently sat down to talk about the upcoming second season of the Netflix series and was posed the question of whether or not he'll appear in the Infinity War movies.
"I have not received that call," Cox says. "Can you imagine? That would be the coolest thing ever."
The decisions regarding whether or not to include Cox or Dredevil in a movie is far over his or any actor's head and Cox explained as much. "Marvel TV and Marvel Studios are two very different things," he tells ET. "Even if the character was to appear in that film, that doesn’t necessarily mean I would appear in the film. I would pick a fight with the guy that they pick."
Certainly, none of us want to see Marvel Studios recast Matt Murdock in the Cinematic Universe. "That would be a dream but that’s not something that has been discussed," Cox concluded.
While it's hard to imagine how the Netflix characters, their choice of words, and their dark, gritty, violent styles fitting into the bright, lighthearted world of the MCU on the silver screen, Infinity War is where it would happen. The Russo Brothers, who are directing both Parts I and II starting later this year, told ComicBook.com that the idea of Infinity War is, "the Marvel universe unites to battle the greatest threat to the world and universe that you’ve ever seen." If there was ever a chance for the crossover to happen, it's 2018 and 2019.
