The series is based on the comic series of the same name by Steve Niles and Damien Worm, adapted for television by Damian Kindler.

Netflix ordered a first season of ten episodes on September 28, 2018, and directors for the season included Damian Kindler, Director X, Megan Follows, Mina Shum, and David Frazee.

The show was produced by High Park Entertainment and IDW Entertainment, with Steve Niles himself serving as one of the executive producers.

Megan Follows, who plays Edith Mooreland, also directed some episodes of the series.

Maxim Roy was cast in a recurring role as the warlock Alice Harlow in October 2018.

Filming for the first season took place on location in Cambridge, Ontario, from September to December 2018.

Netflix cancelled the series after just one season on March 30, 2020, only about two months after its premiere.

On Rotten Tomatoes, the series held a low approval rating of 29%, with critics citing unfinished plotlines, though some found it quirky and entertaining and regretted its early cancellation.
