Prime your proton packs, because it's not long now before the Ghostbusters reboot haunts theaters worldwide. We've already seen a few promo photos and set shots from the film, but today we've got our first honest-to-goodness trailer. And oh boy, does it have us intrigued. The new supernatural-ass-kicking squad stars Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones, all with distinct skills and personalities. The teaser runs for about two and a half minutes and features plenty of ghouls and other Ghostbuster staples, such as the gang's iconic uniforms, the Ecto-1, and the classic theme tune. July 15th can't come soon enough.
