In 2025, she continues to command the screen, leading the ITV crime drama Protection.

Born in Oldham, Greater Manchester, Finneran first gained attention in the late 1980s. She is best known to global audiences as the calculating lady’s maid Sarah O’Brien on Downton Abbey, a role she played from 2010 to 2012.

Why Siobhan Finneran is Considered a Versatile British Actress
Finneran’s career demonstrates a deliberate avoidance of typecasting. She has moved fluidly from gritty independent film (Rita, Sue and Bob Too) to prestige period drama (Downton Abbey), from broad comedy (Benidorm) to tense crime thriller (Happy Valley). Her continued presence on stage at venues like the Donmar Warehouse and the National Theatre further reinforces her reputation as a performer of significant range.
Her character Sarah O’Brien remains one of the most discussed figures in Downton Abbey history. The ambiguity around her exit — and the cliffhanger nature of her final scenes — has kept the conversation alive among fans even years after her departure.
