Marvel has tried the Fantastic Four on screen three times before and never quite landed it. The Fantastic 4: First Steps is the first attempt made inside the MCU — and the first with a cast this strong.
Here's the full lineup, why Galactus is the right villain, and how the film feeds directly into Avengers: Doomsday.
The Cast
Directed by Matt Shakman, who made WandaVision — a genuinely smart hire, because that show proved he can handle period aesthetics and strange tone shifts without losing the emotional thread.

Pedro Pascal as Reed Richards / Mister Fantastic
Vanessa Kirby as Sue Storm / Invisible Woman
Joseph Quinn as Johnny Storm / Human Torch
Ebon Moss-Bachrach as Ben Grimm / The Thing
Ralph Ineson as Galactus
Julia Garner as the Silver Surfer
Paul Walter Hauser and Natasha Lyonne in supporting roles
That is an unusually serious cast for a superhero film. Vanessa Kirby and Julia Garner both come from prestige drama. Ebon Moss-Bachrach and Joseph Quinn broke out in The Bear and Stranger Things respectively. Nobody here needed a franchise.
Ralph Ineson as Galactus is the casting that tells you the tone. Ineson's voice — deep, gravelled, genuinely unsettling — is why he was the terrifying father in The Witch. You do not hire him to play a villain who explains his plan.
Why Pedro Pascal as Reed Richards Works
Reed Richards is a hard role. He is the smartest man alive, which makes him easy to write as cold, and he is a father figure to the team, which makes him easy to write as dull.
Pedro Pascal's whole register solves that. His most successful roles — Joel in The Last of Us, Din Djarin in The Mandalorian — are men carrying enormous responsibility for people they love and failing to say so out loud. That's Reed Richards exactly.

He also brings warmth to characters who are written closed-off, which is the specific thing every previous Fantastic Four film got wrong. For the full story on how he got here, see our Pedro Pascal career breakdown — twenty years of nothing before Game of Thrones.
Galactus Is the Point
Previous Fantastic Four films famously reduced Galactus to a cloud. That was a failure of nerve, and it's the reason those films are remembered the way they are.
Galactus is not a supervillain. He is a cosmic force who consumes planets to survive — closer to a natural disaster with a face than to someone you can negotiate with. He has no personal grudge. He is simply hungry, and your world is food.
That's a fundamentally different kind of threat from what the MCU usually stages. You cannot punch him into submission and you cannot appeal to his better nature. The Fantastic Four have to out-think him, which is the whole reason they're the right team for this story.
Julia Garner's Silver Surfer matters here too. The Surfer is Galactus's herald — the one who finds the planets — and the character's arc is about complicity and conscience. Casting an actor of Garner's calibre suggests the film is taking that seriously rather than using her as a set piece.
How It Connects to Avengers: Doomsday
This is the part most people are searching for, so plainly: the Fantastic Four's arrival is a setup for the larger MCU event.
Two threads connect them. First, Doctor Doom is historically the Fantastic Four's archenemy — his rivalry with Reed Richards is the defining relationship in that corner of Marvel comics. Doom being the Doomsday villain while the Fantastic Four are being introduced is not a coincidence.
Second, the film reportedly takes place in its own universe rather than the main MCU timeline, which fits neatly into the multiverse framework. If you need that framework explained, our Multiverse Saga breakdown covers it in plain terms.
Worth stating clearly: Marvel has not confirmed the specifics of how these films connect. What is confirmed is that both exist, both involve Doom's world, and Marvel has been building toward a convergence for years.
Should You Watch It Before Doomsday?
Yes — and it's a low-cost watch, since it's a self-contained introduction rather than a film requiring homework.
