Kevin Feige teased some rumoured adaptations based on the company's properties.
He told Entertainment Weekly that Edgar Wright's Ant-Man film is "still nebulous but definitely in the works".
Feige said that the Scott Pilgrim Vs. the World director "has "developed an excellent draft recently".
Regarding a Guardians of the Galaxy movie, he said, "There's an opportunity to do a big space epic, which Thor sort of hints at, in the cosmic side of the [Marvel] universe."
He also explained that there was a potential for an Inhumans film, which would - similarly to Guardians - take the form of an ensemble film like the those of the X-Men franchise and The Avengers.
A second draft of Ant-Man was reported as complete earlier in the year.
A Black Panther movie is also in the works.
