First Steps director Matt Shakman was discreet when questioned about Robert Downey Jr.’s role in the post-credits scene, choosing not to reveal any details and leaving the discussion to fans.

The Russo Brothers have warned fans to wait through the credits when they watch The Fantastic Four: First Steps for an Avengers: Doomsday tease, while Robert Downey Jr. is teasing his Doctor Doom research.

Curious why one nation’s seat sat empty during the Future Foundation summit in the new Marvel movie? The Fantastic Four: First Steps plants a subtle but significant clue involving Latveria that ties directly to one of Marvel’s most iconic villains,

“He goes from being the nerdy scientist who’s locked away in the lab, to the husband and the father who’d do anything to protect his family, to the guy who’s leading the Avengers. I realized that the version we were building had to have all of those elements.”

The familiar Baxter Building featured in The Fantastic Four: First Steps will be seen again in Avengers: Doomsday, Marvel boss Kevin Feige has said, sparking speculation over what this means for the fate of the Fantastic Four's version of Earth.

The new "Fantastic Four" movie does Marvel's First Family justice by grounding the story and delivering plenty of action, writes our reviewer.
