Michael Green and Bryan Fuller have decided to leave the Starz drama, American Gods, as its showrunners.

The decision came after the two clashed with producer FremantleMedia over the budget and creative direction of the series. There are reports claiming that Green and Fuller have been demanding for an increase in the show's budget for Season 2.

A source revealed that the duo's budget was already nearing $10 million per episode. As of late, no new showrunners have been named.

Neil Gaiman Won't Serve As Co-Showrunner

Rumors had swirled that Neil Gaiman will come on board as the series' new co-showrunner. The book author, however, immediately debunked the claims and said that there's no truth to it.

Gaiman, however, revealed that he will be working as a showrunner for UK's Good Omens. After his contract ends, he will retire from running a TV show and go back to writing novels.

Bryan Fuller Exits 'Star Trek: Discovery'

Meanwhile, this is not the first that time Fuller has bowed out of his role as showrunner. He also left CBS' Star Trek: Discovery following several delays in production. However, even though Fuller will no longer be working with Starz for American Gods, he is still tied to Apple's Amazing Stories. Green, on the other hand, is still helming the Netflix drama, Raising Dion.

American Gods is a TV adaptation of Gaiman's supernatural novel of the same title, which chronicles the conflict between the old and the new mythological world. The series centers on an ex-convict named Shadow Moon (Ricky Whittle) who is struggling to survive following the death of his wife.

Shadow Moon soon meets a charismatic con man named Mr. Wednesday (Ian McShane) and he asks him to become his bodyguard. As their journey begins, Shadow Moon discovers an entirely different world from what he is used to.

'American Gods' Season 2 Renewal

American Gods Season 1 premiered on Starz on April 30, and it was immediately picked up for a second season on May 11 after only two episodes. Season 1 had a total of eight installments and it wrapped up on June 18. The premiere for Season 2 is expected to take place sometime next year.

Majority of the script for Season 2 has already been written, so, even though Green and Fuller will no longer be part of the production, American Gods will still be a go.

Other than Fuller and Green, other executive producers of American Gods include Adam Kane, David Slade, Stefanie Berk, and Gaiman.
