Undoing Martin Parker is a comedy coming to BBC1 in 2023. It's set in Manchester in the last days of Margaret Thatcher's Conservative government in 1990, and sees Game of Thrones star Conleth Hill play a businessman whose life is spiralling out of control. 

Penned by Sian Gibson and Car Share writer Paul Coleman, the six-part series follows Martin Parker, an ambitious self-made impresario who appears to have it all. Diane, played by Rosie Cavaliero, is Martin's long-suffering wife.

Sian Gibson who, as well as co-writing the series also stars as a local hairdresser, says: “Luckily my fashion sense hasn’t changed since 1990 so it’s a dream to be reliving my youth and dusting off my crimpers with this amazing cast and wonderful team.”

Undoing Martin Parker behind the scenes and filming news

Filming is due to commence on the six-part series in Manchester early next year. Undoing Martin Parker was commissioned by Jon Petrie, Director of Comedy for BBC One and BBC iPlayer. It is co-created and written by Paul Coleman and Sian Gibson, produced by Gill Isles, executive produced by Kate Daughton for Boffola pictures and Head of BBC Comedy Tanya Qureshi and will be co-produced with Lookout Point.

Writer Paul Coleman says: “Thrilled to be writing this series and working with such a wonderfully talented cast, who are all helping us shine a much needed light on the themes of family feuds, revenge and top-loading VCRs.”

Jon Petrie, Director of Comedy, says: “Sian and Paul have created an irresistible gang of comedy characters and a world packed with joyful nostalgia. The quality of their writing is matched by a fantastic cast and we’re incredibly excited to introduce Martin Parker and bring this lovable rogue to BBC audiences in 2023.

"The actors loved going back to 1990. The writers as well. They all  love a lot of nostalgia, retro jokes and stuff. So there's a lot of that in this comedy. It's an interesting period of time, with the downfall of Thatcher. You know, you sometimes see stuff earlier in the 1980s, but the early 1990s is quite an interesting time. It's good fun, especially seeing adverts and things from that era on screen."
