First Steps has cemented itself as one of Marvel's biggest films in recent years, bringing the first family into the Marvel Cinematic Universe in glorious fashion, delivering what many have already proclaimed as the best live-action iteration of Fantastic Four to date (not that there's much competition to begin with).

Having been consistently building for the last 17 years, the Marvel Cinematic Universe timeline is quite complicated... and the arrival of The Fantastic Four: First Steps doesn't exactly make things much clearer.

The Fantastic Four: First Steps is set during the 1960s, unlike its predecessors, which were set during modern times and don't tell their origin stories. In addition to that, the film ( alongside Thunderbolts) has also set the stage for Avengers: Doomsday, which is set for a December 2026 release.
