"Something big is going to happen," says Wiig's character.
"The word you are looking for is apocalypse," adds McKinnon.
The new trailer includes more scenes with Hemsworth, who plays their assistant and seems to be involved in the nefarious things that are going on, and a better look at Slimer, the ghost from the original 1984 film.
It hasn't been an easy journey for the new Ghostbusters so far. Feig's version was met with sexist criticism for rebooting the classic story with an all-female cast, and then the first trailer was reportedly one of the most disliked in YouTube history (although it remains to be seen if this is due at least in part to the continued disapproval of a female cast).
