The episode – once again starring David Tennant and Michael Sheen – has now been filmed, with Gaiman having exited the project following accusations of sexual assault, which the author has strongly denied.
However, Sheen has now seemingly cast some doubt over whether fans will ever get to see the episode at all.
"I hope people get to see it, but that, to a large extent, is out of our hands."
RadioTimes.com has approached Amazon Studios for comment.
Allegations included claims that Gaiman engaged them in "rough" sex and BDSM without their consent. The novelist has firmly denied any non-consensual or illegal conduct in a statement.
"I'm far from a perfect person, but I have never engaged in non-consensual sexual activity with anyone. Ever.”
Gaiman's full statement is published on his blog.
He was asked by one of the interviewers: "Someone you've worked with, a friend, has been cancelled for some quite serious allegations. How has that affected you?"
Tennant responded, saying: "We're doing Good Omens again. We're going back to do the final. We're doing a final. There's been a slight rejig with the personnel.
