Requiem

Requiem is a co-production between New Pictures for the BBC and Netflix, and was written and created by Kris Mrksa and directed by Mahalia Belo.

The series was produced by New Pictures, the same production company behind the acclaimed drama The Missing.

All six episodes premiered simultaneously on BBC One and BBC iPlayer on 2 February 2018, before becoming available internationally on Netflix on 23 March 2018.

Filming began in March 2017, with principal photography taking place in Wales from June 2017, supported by funding from the Welsh Government.

St David's Hall in Cardiff was used to stand in for a London venue during filming.

Cefntilla Court (also spelled Cefn Tilla Court) in Usk, Monmouthshire, served as the country house, Dean House, where the character Matilda stays, while other scenes set in the fictional town of Penllynith were filmed in Newport and Dolgellau.

On Rotten Tomatoes, the series holds a 73% approval rating based on 22 critic reviews, with critics describing it as a mysterious thriller with Lynchian elements combined with a compelling character study.
