From subtle nods to future villains to multiverse tributes, Fantastic Four: First Steps fills its runtime with cameos that matter.

Although the stars of the 2005 Fantastic Four movie don’t show up during the movie like many Marvel fans would have wished, the stars of the 1994 The Fantastic Four film do. The actors, Alex Hyde-White, Rebecca Staab, Jay Underwood, and Michael Bailey Smith appear near the beginning of the movie in a crowd, cheering "Thank you, Fantastic Four!"

First Steps introduce none other than Doctor Doom with its post-credits scene and here is everything you should know.
