Three decades after the classic film 'Ghostbusters' premiered in 1984, the cast is back together again, thanks to a special reunion issue by Entertainment Weekly.

Bill Murray, Dan Aykroyd, Ernie Hudson, and Sigourney Weaver reunited with Annie Potts and director Ivan Reitman to look back at the legacy of the supernatural comedy 'Ghostbusters', its 1989 sequel 'Ghostbusters II', and Ray Parker Jr.'s "Ghostbusters" song that won the film an Academy Award.

Apparently, the cast at the time predicted that the film was going to be a success.

"I knew it was gonna be a huge movie," said 'Groundhog Day' actor Bill Murray in an interview with Al Roker during the Entertainment Weekly cover shoot.

"At that point, we were still watching Yankee Doodle Dandy on TV, so I thought we had a shot," the 64-year old comedian added, who was only in his 30's when 'Ghostbusters' premiered.

The 'Charlie's Angels' star added that the "Ghostbusters" car had a celebrity status of its own, and when they drove it around town, it had an effect on real cops as well.

"We had that car. And in the uniforms, with the car, even the cops thought we were above them somehow, running red lights, [going the] wrong way on a one-way street," Murray said.

He also revealed what the film's "ectoplasm" was actually made of: "a disgusting combination of corn syrup and starch and some sort of an adhesive and a kind of a poison that's used on chinch bugs," the actor joked.

When asked if he is open to making another movie, a 'Ghostbusters III' with the original cast, the 'Saturday Night Live' host was doubtful.

"It's really hard to recreate something that was so beautiful, so wonderful," Murray said.

While Murray remembered 'Ghostbusters' as a film that gave out huge laughs, for Ernie Hudson, it was different. In a special write-up in Entertainment Weekly, Hudson, or the fourth Ghostbuster, revealed how his role as Winston Zeddemore changed his career, and even his life.

"I've survived this 30 years because of what I learned on Ghostbusters; you learn to adjust. What I did was I turned to TV," Hudson wrote.
