Ellen Robertson

She attended Cambridge University and was a member of the Cambridge Footlights. Whilst studying in school in Oxfordshire she attended a playwriting workshop with Charly Clive with the pair first performing together in 2009 and later travelling together during their gap year. Robertson lived with Clive after Clive was diagnosed with a brain tumour in 2016 and had to return to the UK having previously moved to New York. They later turned the experience into a stage show Britney, the name Clive had given to her tumour, which was performed at Edinburgh Fringe Festival and the Soho Theatre in London. Proceeds from the show were donated to The Pituitary Foundation.

She also appeared on stage in Mike Bartlett play Snowflake in Oxford and reprised the role at the Kiln Theatre, directed by Clare Lizzimore in 2019. She could be seen as Poppy in Sarah Phelps television series The Pale Horse in 2020. On stage, she appeared in the world premiere of Mike Bartlett play Mrs Delgado in 2021 at the Old Fire Station, Oxford. Britney was adapted for television, starring both Robertson and Clive, and broadcast on BBC Three in 2021 with a cast including Omid Djalili and Tony Gardner alongside the pair. The following year, Robertson and Clive returned to the Edinburgh Fringe Festival with their show Britney: Friends and Nothing More, named after a comedy song Clive wrote for Robertson after she came out.

Robertson appeared in Bong Joon Ho directed feature film Mickey 17, alongside Robert Pattinson (2024) and appeared in the Black Mirror episode Joan Is Awful alongside Annie Murphy on Netflix (2024). She was cast in Lena Dunham’s 2025 Netflix series Too Much. That year, she was cast in Vladimir alongside Leo Woodall and Rachel Weisz.
