On July 13, 2018, it was announced that HBO had given the production a straight-to-series order. Joss Whedon will serve as a writer, director, executive producer and showrunner for the series. The series landed at HBO after a bidding war with other networks and streaming services including Netflix.[2][7][8]

Whedon explained the title at Comic-Con 2018:

They, themselves are not called that [The Nevers] in the show. It’s a phrase that’s meant to evoke a sort of reaction to their oddity, to what is considered unnatural. The idea that you should never be like this, you should never have existed. Something is not the way it should be, and you don’t have the right to have whatever weird power or ability that you have. And that idea, that some people are not of the natural order, is fascinating to me. I don't agree with it. But to me, it’s one of those things where you take something negative, and you wear it as a badge of honor, basically. Certain things could never happen - they’re happening. And the people they’re happening to are taking their place in the world.[9]

Executive producers include Bernadette Caulfield, Jane Espenson, and Doug Petrie. Espenson and Petrie, who worked with Whedon on Buffy the Vampire Slayer, will also serve as writers.[10] Laurie Penny is also part of the series' writing staff.[11] Gemma Jackson serves as production designer.[12]

On July 4, 2019, Whedon announced that principal photography had started, with filming occurring in London.[10][13] In July 2019, it was reported that scenes had been filmed at Trinity Church Square,[14] and in the New Wimbledon Theatre area.[15] In August 2019, scenes were filmed at Chatham Historic Dockyard in Kent.[16]

In late January, shooting took place at Joyce Grove, a country house estate in the Jacobean style. The building will double as The Orphanage.[17]

Due to the lack of studio space in London, HBO worked with Adrian Wootton, CEO of Film London and the British Film Commission to find warehouse spaces and old industrial spaces they could base the production in.[18]
