There is no Dana, there is only Zuul. Oh, wait. There IS a Dana, and she's coming back to the Ghostbusters universe.
"It's going to be crazy working with the guys again!" Weaver said.
The interview is pretty cagey about revealing much, but it does say Weaver will be back as Dana, and that Bill Murray and Dan Aykroyd will also return. Harold Ramis, who played Ghostbuster Egon Spengler, died in 2014.
The new film is due out July 2020.
