Last Tango in Halifax writer Sally Wainwright has revealed that the show could have a long future ahead.

Starring Derek Jacobi and Anne Reid as love-struck septuagenarians Alan and Celia, Season 3 of the comedy-drama is currently airing on Sunday nights on BBC One.

Asked if she’d like to write a fourth season, Wainwright told the BBC: “Yes! I think there’s huge mileage [in the characters].”

Discussing Last Tango in Halifax‘s darker storylines and the conflict that’s arisen from the arrival of Sherlock star Rupert Graves’ character, Gary, the writer commented: “There’s not much drama in people being happy – it’s all nice and wonderful, but we felt that we needed to use [Alan and Celia’s] backgrounds because they’ve not seen each other for 60 years and they’ve got married really quickly.”

She added: “There’s vast swathes of their previous lives that actually neither of them know anything about and really the story is about something from Alan’s past that he’d forgotten about himself.”
