“It’s a reboot, not a remake,” Melissa McCarthy explained on  “I know it’s weird that they say ’30 years ago,’ but in this movie it’s like the first one didn’t happen. It’s that great story but told totally differently.”

Aside from that, though, the story is much like the original 1984 movie and the 1989 sequel. McCarthy says, “it’s the same thing of four unlikely heroes: it’s in New York City [and] ghosts are taking over.”
