"Ghostbusters: Frozen Empire" merges original cast and new talent 40 years after the movie premiered

Returning to the supernatural streets of New York in "Ghostbusters: Frozen Empire," the original "Ghostbusters" cast — actors Bill Murray, Dan Aykroyd, Ernie Hudson and Annie Potts — bravely confronted not just a new ghostly threat, but their old nemesis: Those massive proton packs.

"Wearing the damn packs, they are really heavy," said Murray. "Wearing the pack a long time ago was miserable. Wearing the pack now is like torture."

In a mix of past and present, the iconic crew from the 1984 classic "Ghostbusters" has joined forces with newcomers Paul Rudd and Mckenna Grace, 40 years after it was first released.
