"Fantastic Four: First Steps" just hit theaters on July 25, starring Pedro Pascal, Vanessa Kirby, Joseph Quinn, and Ebon Moss-Bachrach.
Set in Earth-828, the movie follows the team as they look out for Sue Storm's newborn son Franklin.

How Doctor Doom entered the picture
Stick around after the movie—there's a mid-credits scene set four years later where Sue is reading to Franklin and a mysterious figure appears holding Doctor Doom's mask.
The big surprise? He's played by Robert Downey Jr., hinting at his arrival in the MCU.
Tribute to Jack Kirby
The last post-credit moment features a classic Fantastic Four cartoon as a tribute to legendary comic creator Jack Kirby.
The Earth-828 reference is actually a sweet shoutout to Kirby's birthday on August 28.
