As the writers slave over another draft of the Ghostbusters 3 script -- with production hopefully beginning later this year -- some more news regarding the film's storyline has slipped out across these internets, with one aspect being an exclusive to Cinematical.

Possible spoilers for Ghostbusters 3 to follow ...

First up is the news that Bill Murray has confirmed his other-worldly role in the film. A few months back, Sigourney Weaver had let slip that Murray was going to be playing a ghost in the film -- a rumor that was later squashed by folks who claimed that particular storyline was featured in a very old draft. However, Murray has now gone on record as not only disliking the second Ghostbusters movie (something he's said before) and thinking that Groundhog Day should've been a bigger hit, but also noting that he would only return to the Ghostbusters franchise if they made his character a ghost. He says, "I said to them, 'I'll do it if you kill me off in the first reel.' So now they are going to have me as a ghost in the film." Murray as a ghost? I hope it works. What do you think?

Meanwhile, as most talk revolves around the returning actors and the identity of the new recruits, little has been said about the film's mythology and who (or what) the Ghostbusters will be battling this time around. Well, Cinematical has it on very good authority that as recent as this past summer, the central mythology of the sequel was being based on Zoroastrianism, which is one of the earliest religions on record. Like with most religions, the war between good and evil is at its central core, and in terms of evil there's Ahriman: the god of darkness, the eternal destroyer of good, personification and creator of evil, bringer of death and disease.

Is Ahriman the film's villain?

Unfortunately, we cannot confirm that Ahriman is or isn't the villain, but if the writers are still working with Zoroastrianism as the basis for the film's mythology, then it would make sense that Ahriman would play a big role in unleashing evil spirits into our world, much like Gozer did in the first film. Ahriman also existed as a character in Highlander: The Series, where it was said that the demon returned to Earth every thousand years to wreak havoc. Like we said before, this is all speculation based on the news that Ghostbusters 3 will revolve in some way around the ancient religion of Zoroastrianism. Of course, as we hear more, we'll let you know.
