In December 2019, HBO and Sky announced they had given a series order to
Landscapers, a true-crime miniseries written by Ed Sinclair and originally intended to be directed and executive produced by
Alexander Payne, with Olivia Colman attached to star; Sinclair had created and wrote the series with Colman in mind for the part of Susan Edwards. In October 2020, Alexander Payne exited the project due to scheduling conflicts and was replaced by
Will Sharpe. David Thewlis was cast as Christopher Edwards in March 2021.
Principal photography for the series began in March 2021 in Mansfield, Nottinghamshire. The series features a flashback scene; although both Colman and Thewlis are intended to be much younger in the scene, no visual effects or specific makeup were used, with Thewlis commenting "We just put wigs on." Both Colman and Thewlis stated that they did not doubt the culpability of the Edwards in the murder, but that the series was intended to create empathy and an understanding for the couple, with Thewlis stating "what we're asking the audience to decide is not whether they're guilty, because they clearly are, but whether they deserve sympathy" and Colman stating "you do find yourself going, 'God, I wonder, had I had that set of circumstances, what would I do? They're gentle, meek people. What on earth made them do it?" ==Release==
