Are you still holding out hope for see Daredevil and the Defenders to appear in the 2017 Spider-Man reboot, or team up with the Avengers and Guardians in Avengers: Infinity War?, then hold your hopes up, as Daredevil star Chalie Cox has said there havent been any conversations for that. Cox stated "There was no conversation about joining any of the movies," although he said he would jump at the chance to appear in a Marvel movie. "Who wouldn't want to be in the highest grossing film of all time?"
So unless he's just being coy in order to avoid revealling information he's not supposed to reveal yet, dont expect any of the small screen stars to pop out in the movies in the near future. also as Charlie Cox confirmed that Defenders will start shooting this year, that could very well affect any possible appearances in Spider-Man or Infinity, since both movies will be shooting around the same time as Defenders, so the schedule for the actors could serve as a issue against them appearing in the Big Screen.
