Sean Delaney is best known for his starring role in the first three seasons of the BBC's BAFTA and Emmy winning drama series 'Killing Eve'.  He played Kenny, the son of MI6 chief Carolyn, a computer whizz recruited by MI6 to join the team hunting Jodie Comer's character Villanelle. 

He had a prominent role in the BBC Two fantasy drama series 'Life After Life', playing Teddy, opposite Lesley Manville and Jessica Hynes.

Film credits include playing a younger version of Stephen Graham's character Detective Mulligan in the 2021 Marvel feature film 'Venom: Let There Be Carnage' which starred Tom Hardy, Woody Harrelson and Michelle Williams.

His theatre work includes playing Michael Carney in Jez Butterworth’s triple Olivier Award-winning play ‘The Ferryman’, directed by Sam Mendes and set during The Troubles in 1980s Ireland. He continued to play the role when the production was transferred to Broadway in late 2018 where it won four Tony Awards.  Prior to that, in 2016, he starred as the co-lead in the Hampstead Theatre's production of ‘Labyrinth’, which earned him a place on the long list for the Evening Standard Theatre Emerging Talent Award.  More recently he starred in 'Brilliant Jerks' at the Southwark Playhouse in 2023. 

Sean naturally speaks with a neutral accent, with hints of London. He is from a large Irish family and his range of Irish accents is that of a native. He's perfectly tuned in Dublin and Belfast accents.
