Marvel’s ‘Fantastic Four’ introduces powerful new characters to the MCU, and ends with tease for ‘Avengers: Doomsday’—here’s the ending and post-credits scene, explained.

First Steps marks the fourth attempt to translate the original comic book characters of Reed Richards/Mister Fantastic, Sue Storm/Invisible Woman, Johnny Storm/Human Torch, and Ben Grimm/The Thing to the silver screen. This time, the action will take place in an alternate history/parallel universe set in the ’60s.

"I'm sorry she didn't get a chance to see the finished movie," director Matt Shakman tells EW of the dedication to his late mother, Inez Shakman.
