With two "Iron Man" films already released, "Thor" and "The First Avenger: Captain America" currently in production and "The Avengers" not too far on the horizon, Marvel Studios is building up its slate to a massive crescendo — but what happens after Earth's mightiest heroes assemble on the big screen?

Beyond "Runaways," little is known about Marvel's plans for how to proceed once "The Avengers" lands in theaters. Speaking with MTV News, Marvel studio chief Kevin Feige discussed some of the possible projects they're looking at as follow-ups to the "Avengers" franchise once all's said and done on Iron Man, Thor and Captain America's first big screen team-up.

"I think what Ed Brubaker and Matt Fraction have done with 'Iron Fist' lately is exciting," Feige told MTV News. "I think 'Black Panther' and Wakanda has some amazing potential to be a feature film. 'Doctor Strange,' as you've mentioned. There are some obscure titles, too, like 'Guardians of the Galaxy.' I think they've been revamped recently in a fun way in the book."

Of course, Marvel already has its fair share of established characters that could carry their own film, such as War Machine, Black Widow and — most especially, considering his reported nine picture deal — Samuel L. Jackson's very own Nick Fury. Is it possible that fans will ever see a Fury-centric film?

"I think the answer is yes," said Feige. "I think S.H.I.E.L.D. could be it's own franchise. I think, frankly, 'The Avengers' is going to be told from that point of view more so than any of the other films at that point, so we're going to get an inside look [at how S.H.I.E.L.D.] operates."
