Today Marvel Studios head Kevin Feige spoke with Badass Digest about the potential of moving forward with the next Phase in their plans that may include more then 2 films per year:
I think television is filling some of that now, in terms of bringing out more product. That’s certainly the idea with the Netflix shows. But I don’t know that we will necessarily say “Okay, we’re now moving strategically to three a year, now we’re moving to four a year.” What I think is more likely – if [knocks on wood-like table] the next group of movies work and people want to see additional stories – we’ll have too many franchises and you can’t do one of each franchise every two or three years. We’d have to move to three a year, but that would have to be a natural move if it were to occur. We’d have a [script] draft, we’d have a filmmaker, we’d have a character the audience wants to see – let’s slot in a place for a third one. Or a fourth one.
Marvel's model will be modular franchises - three films each - that surround the larger AVENGERS franchise, which switches out characters.
