People in the poster appear to be missing fingers or legs - common hallmarks of Gen-AI models - but the studio says that's not the case.

“The Fantastic Four: First Steps” tells the story of Marvel’s first family and stars Pedro Pascal as Reed Richards/Mr. Fantastic; Vanessa Kirby as Sue Storm/Invisible Woman; Ebon Moss-Bachrach as Ben Grimm/The Thing; and Joseph Quinn as Johnny Storm/The Human Torch.

In response to a wave of backlash this morning, Marvel has denied the use of AI in the creation of a new "Fantastic Four: First Steps" poster.
