New details about the upcoming 'Fantastic Four' movie were unveiled during Marvel's San Diego Comic Con panel.

A new Fantastic Four including Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach makes Marvel movie debut in "First Steps" trailer.

Thankfully, the new teaser for Marvel’s Fantastic Four: First Steps doesn’t spoil all that much of the film, but it does give you a sense of just how big a problem Galactus is going to be for the MCU.
