He might have already confirmed that Spider-Man: Homecoming won't have ANY links to the Defenders on Netflix (including any Easter Eggs, but that just sounds like a double dare to find them, to be honest), but it sounds like Eric Carroll might have plans to bring him in for the sequel.
Or at least he'd like to.
With Spider-Man: Homecoming heading to cinemas soon, Carroll told CinemaBlend that he'd love to see the blind superhero encounter the MCU's Peter Parker on screen:
“[Daredevil is] not specifically referenced in [Spider-Man: Homecoming], no. I think that's something we all think would be really fun, and it's definitely a card I would love to see played, if not sooner rather than later.”
Would that mean a cross-over with Netflix's version of the character? Or a wholly new one? There has been a pretty clear line drawn between the shows and their big screen counterparts, and repeated assurances that we won't see any of those characters crossing over.
There have been examples of movie characters going from the movies to the small screen - like Nick Fury, Peggy Carter and Phil Coulson - but so far nothing flowing the other way. Maybe Daredevil will be the first one? He and Spider-Man have a long and storied history in the comics and it would be great to see them reunited on the big screen, provided it wouldn't have to mean more complex negotiations with Sony, of course.
Personally, I'd prefer to see him fight The Punisher or Kingpin or both, but that's just me.
