Watch the First Ghostbusters Trailer

It’s been more than three decades since a team of scientists saved New York City from a phantasmagoric crisis, and now, a new generation of phantom-fighters is taking over.

The long-awaited trailer for Paul Feig’s Ghostbusters reboot, starring Kristen Wiig, Melissa McCarthy, Leslie Jones and Kate McKinnon, dropped Thursday morning, offering a glimpse of the director’s revision to a now-classic tale. Based on two-and-a-half minutes of footage, it appears we can expect chalkboards full of physics equations, slapstick comedy and plenty of ectoplasmic residue from the movie, which hits theaters July 15.

As for the decision to cast four women in the leading roles, in contrast to the original film’s four male actors, Feig said at the trailer’s sneak preview Wednesday, according to Deadline, that it’s not worth fussing over. “The first movie worked because it had four of the funniest people,” he said, “and I just want the funniest people, and the funniest people are these women.”
