Delaney has written, created and executive produced the series, led by Gugu Mbatha-Raw (The Morning Show) and David Oyelowo (Selma).

Mbatha-Raw stars as Jane, a young woman who is afforded the opportunity to move into a spectacular, ultra-minimalist house designed by a mysterious architect, played by Oyelowo.

In order to live there, however, she must abide by the architect’s list of onerous rules. With the house beginning to take an unnerving hold over Jane, she makes the disturbing discovery that the previous occupant, Emma, died in the house.

As Jane begins to uncover unsettling similarities between herself and Emma, she begins to suspect she might suffer the same dreadful fate.

Gugu Mbatha-Raw commented: “I'm so excited to work with this amazing team on such a compelling story in my debut role as actor/producer.”

David Oyelowo added: “This story is mind-bending in its clever construction and intricacy. I can’t wait to see it, let alone be in it. Plus, I’d go anywhere to work with my friend Gugu again.”

Series creator JP Delaney said: “Having written for the screen in a previous career, it’s long been a dream of mine to adapt The Girl Before, but I was determined to only do it if I could find partners who wanted to pursue high quality, classy storytelling above all else. You really couldn’t get a more quality-focused line-up than 42, the BBC and HBO Max – and we’ve already attracted world-class talent in the shape of Lisa, Gugu and David.”
