Trivia: This film marks the third time that a first Fantastic Four adaptation of a planned franchise was released during the fifth year of a decade. The first to get a theatrical release was directed by Tim Story and released in 2005, being successful enough to warrant a 2007 sequel. The second was the Josh Trank-directed "Fant4stic" in 2015, which ended up being a major box office bomb.
Trivia: Steven Yeun was originally cast as Sentry, but dropped out of the role in late 2023. He cited the SAG-AFTRA strike and shifting schedules as the main reasons.
