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

The first trailer for Marvel Studios' "The Fantastic Four: First Steps" has arrived. Stars of the film, including Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach, helped debut the highly anticipated trailer in epic fashion, live from the U.S. Space & Rocket Center in Huntsville, Alabama, in front of a Saturn V rocket.

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.
