As a part of its upfront presentation today, CBS released a new full-length trailer for the summer series Extant. Last week's 60-second trailer revealed that astronaut Molly Woods (Halle Berry) somehow returned home from a 13-month solo mission in outer space with an unexpected pregnancy. This new trailer shows how that may have been possible, while providing new details about the Humanix Project, lead by Molly's husband John (Goran Visnjic). Check out the latest footage before this sci-fi series debuts Wednesday, July 2 with the series premiere.
