Marvel Studios celebrated the release of the first Fantastic Four: The First Steps teaser trailer with an event yesterday at the U.S. Space & Rocket Center. The countdown began on YouTube about an hour prior to the "launch" in Huntsville, Ala., which was hosted by Angelique Roche. Viewers saw various images from the museum during the "Future Foundation Live Broadcast," as they awaited the trailer's premiere. Cast members Pedro Pascal (Mr. Fantastic), Vanessa Kirby (Invisible Woman), Ebon Moss-Bachrach (Thing) and Joseph Quinn (Human Torch) then joined Roche on the stage. First Steps hits theaters July 25th. The film is the second reboot of the Fantastic Four film series; the original 2005 adaptation starred Ioan Gruffudd, Jessica Alba, Chris Evans and Michael Chiklis, while a 2015 reboot featured Miles Teller, Michael B. Jordan, Kate Mara and Jamie Bell.
