Marvel’s Cinematic Universe covers the big summer blockbusters as well as their offerings on Netflix and regular television. Speaking to SlashFilm, Marvel Television’s president Jeph Loeb threw some cold water on speculation that Daredevil or Jessica Jones might appear in one of the upcoming films.
The reason comes down to the differences in speed between film and television productions
The reason why you won’t see characters from Daredevil, Jessica Jones, Luke Cage or Agents of SHIELD in films like Avengers: Infinity War? It comes down to the differences in speed between film and television productions. "I can tell you that part of the challenge of doing this sort of thing is that the movies are planned out years in advance of what it is that we are doing," Loeb told SlashFilm. "Television moves at an incredible speed." He went on to say that it was often difficult to pull a lead character such as Luke Cage or Daredevil from their shows. "I need Mike [Colter] to be in a television show."
There have been some movie-to-television connections, particularly with Agents of SHIELD, which has seen Samuel L. Jackson, Jaimie Alexander, and Cobie Smulders stop by to appear in an episode or two. Despite the logistical hurtles, Loeb noted nothing is being ruled out. Maybe we'll someday see some character appearing in one of the upcoming blockbusters.
