This mini-series was originally scheduled to be broadcast on the ITV Encore television channel in 2018. However, problems with another ITV mini-series, Hatton Garden (2019), caused the broadcaster to bring forward the broadcast of Bancroft to December 2017 to replace the other series.
This seems to have parallels to the story of Los Angeles Police Det. Stephanie Lazarus and her murder of romantic rival Sherri Rasmussen who was brutally beaten, bit and shot three times in the chest on Feb. 24, 1986.
The first series of Bancroft was said to be one of ITV's best performing dramas of 2017 with an average of 6.7 million viewers and a 25 percent audience share.
