Now Aykroyd has confirmed his long-rumoured return to the role of Ray Stantz during an appearance on the Joe Rogan Experience podcast.
"Ivan Reitman's son Jason has written a new movie, called — well, it's gonna be Ghostbusters, the third movie," he explained.
"It'll be all or most of the original people. And then young stars […] It's gonna be great.
"I'm so excited about it, and it's just wonderful to be able to [go] back and revisit that. I don't do the pictures anymore much, and I'm in that one."
Aykroyd has previously said he was "hoping" Bill Murray would also sign-on to once again play Dr. Peter Venkman, and Reitman confirmed the Groundhog Day and Lost in Translation star has read the new script.
Sigourney Weaver has also confirmed she will reprise her role as Dana Barrett, and Hudson and fellow co-star from the original movies, Annie Potts, have hinted they will also be involved.
In June it was announced Paul Rudd would join the cast with the Ant-Man star saying: "I can't wait to join the cast this fall for Ghostbusters. In fact, I'm sliming myself right now."
