Kevin Feige says that Marvel Studio has no plans to do an Avengers and X-Men crossover film.
There has been plenty of talk this year about the possibility of Hugh Jackman's Wolverine joining forces with the Avengers in a future film.
And while Feige admits that it would be fun, there is nothing in the pipeline to make that happen.
Speaking during a Jameson's Done In 60 Seconds Google Hangout online Q&A for Empire magazine, Feige said: "There's certainly no plans right now. Enough amazing things have happened in the 13 years that I've been at Marvel, I never say never to things like that. But I don't think it'll be any time soon.
"'The Avengers' have so many stories to tell. It's not like creatively we need or want to include the X-Men, but as a fan I think it would be fun. It's Phase 27!"
2013 has already been a very successful year for Marvel with Iron Man 3 breaking $1 billion at the box office earlier this summer; following in the footsteps of Avengers Assemble.
Iron Man 3 kicked off Phase 2 of Marvel film, and that will continue this October with the release of Thor: The Dark World.
Captain America: The Winter Soldier, Guardians of the Galaxy And Avengers: Age of Ultron will round off Phase 2.
And Marvel are already planning movies beyond the release of Avengers: Age of Ultron in summer 2015.
The movie boss explained: "The waters have been rising over eight years on 'Ant-Man'. It's been a while so it feels like we're ready to go.
"Phase 3 is in the very, very early days. 'Ant-Man' is the first official one. We're working on a handful of things. We only have two slots a year. And we've got four or five things that are in the works right now."
