The new Ghostbusters reboot, starring Kristen Wiig, Melissa McCarthy, Kate McKinnon and Leslie Jones, is out July 15 and they've just released the first trailer.

Freaks & Geeks creator Paul Fieg directs, and Chris Hemsworth has the Annie Potts role here as Ghostbusters HQ receptionist. They've updated Ray Parker Jr's theme song for 2016, too. Check out the trailer:
