The MCU introduces Marvel's first family in "The Fantastic Four: First Steps," but what do you need to watch first?

First Steps gives a spectacular new story about Marvel's First Family with a bold, breathtaking superhero blockbuster.

At the core of First Steps are Pedro Pascal, Vanessa Kirby, Joseph Quinn, and Ebon Moss-Bachrach as Reed Richards, Sue and Johnny Storm, and Ben Grimm. Each slips easily into their role like a customized astronaut suit, but special praise has to go to Kirby and Moss-Bacharach for giving the ensemble its real heart.
