Kevin Feige, Marvel Studios' President of Production says co-Co-president Louis D'Esposito has directed "a little something that we're going to reveal in the coming months."

Speaking to SHH Feige, who is rapidly becoming my favorite Hollywood Exec, revealed that Marvel will have a secret something revealed in a few months that apparently already been filmed. My best guess is that it's more shorts but you never know with Marvel [and that's why we like them]. (Culture, Kevin Feige, Marvel Studios)
