Clarifying why it's been difficult to crossover the characters from Marvel's Netflix shows into the feature films, Marvel Television head Jeph Loeb explained what makes the Marvel Cinematic Universe connected, apart from cameos and guest-appearances.

"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 /Film. "Television moves at an incredible speed. The other part of the problem is that when you stop and think about it, if I'm shooting a television series and that's going to go on over a six-month or eight-month period, how am I going to get Mike [Colter] to be able to go be in a movie? I need Mike to be in a television show."

While the properties all take place in the same universe, Loeb says it's logistically difficult to get the TV actors to appear in the films beacuse of their rigorous schedule.

Quoting the classic Marvel phrase "It's All Connected," Loeb clarified that the properties all link by inhabiting the same world. "As I often get reported by you folks for saying #ItsAllConnected, our feeling is that the connection isn't just whether or not somebody is walking into a movie or walking out of a television show," Loeb continued, "It's connected in the way that the shows come from the same place, that they are real, that they are grounded."

The next Marvel Television project, "Luke Cage," drops September 30 on Netflix.
