The "Ghostbusters" reboot trailer confused a lot of people -- including one of its stars, Melissa McCarthy.

The trailer (which is also the most disliked trailer in YouTube history) made fans wonder if the movie was a reboot or a sequel, since the video begins with the phrase "30 years ago." In a radio interview, McCarthy cleared up that opening sequence.

"It's a reboot. I know, it's weird that they said the '30 years ago' because in this movie, the first one didn't happen. It's that great story, but told totally differently," the actress explained.

So, not a sequel, folks! The new "Ghostbusters" -- which also stars Kristen Wiig, Kate McKinnon, and Leslie Jones -- does not exist in the same universe as the 1984 original.

McCarthy tried to point out the ambiguity of that opening, but The Powers That Be shut her down.

"Believe me, the question was asked," she said. "I was like, 'I think that's very confusing,' but then everyone said, 'We don't care what you think.'"
