Does Galactus Change Size in Fantastic Four (2025)? Director Confirms the Truth

What did Matt Shakman reveal about Galactus’ size?

Director Matt Shakman has confirmed that Galactus’ size is not fixed in The Fantastic Four: First Steps. Speaking in an interview, Shakman explained that Galactus’ height changes throughout the movie, ranging from 700 feet to 1200 feet, depending on what he is standing next to.

The decision was intentional, with Shakman noting that “he changes by hundreds of feet” to remain visually imposing relative to his surroundings — whether towering over skyscrapers or matching the Golden Gate Bridge.

Why is Galactus’ size inconsistent in the movie?

According to Shakman, keeping Galactus’ scale flexible was a filmmaking necessity. He compared the approach to his past work on Godzilla, where the monster’s size also shifted slightly based on perspective. The goal was to maintain cinematic impact, ensuring Galactus always felt overwhelming on screen.

How does this compare to the comics?

In Marvel Comics, Galactus has the ability to alter his size at will using the Power Cosmic. He can shrink to human height or expand to rival entire solar systems. While Fantastic Four: First Steps shows smaller fluctuations in his scale, it avoids fully showcasing this cosmic power.

Could Galactus’ true powers appear in future MCU movies?

Fans speculate that Galactus may return in upcoming Marvel films like Avengers: Doomsday or Secret Wars. If that happens, audiences could finally witness his true size-changing abilities on a grander scale — perhaps even larger than the Celestials seen in Eternals.

Who stars in The Fantastic Four: First Steps?

Pedro Pascal as Reed Richards (Mr. Fantastic)

Vanessa Kirby as Sue Storm (Invisible Woman)
