Siân Brooke on Playing a Belfast Police Officer in Blue Lights

Actor Siân Brooke has spoken about her role in the hit Belfast-set police drama Blue Lights, reflecting on how playing a police officer for four years has shaped her own sense of vigilance in daily life, according to an interview published by The Guardian.

Brooke, who previously appeared in Sherlock and had a brief but memorable role in House of the Dragon, has starred in the BBC series Blue Lights for the past four years. The show is known for its hard-hitting portrayal of policing in Belfast, a city the series depicts as grappling with both past and present tensions.

In the interview, Brooke described how the show's themes of vigilance have carried over into her own life, recounting an episode in which she grew suspicious of activity near her home in London and mentioned it to her husband. She recalled that her husband reminded her she was not, in fact, a real police officer, a moment she found amusing given how deeply the role had influenced her instincts.

Blue Lights has drawn attention for its grounded depiction of policing and community tension in Belfast, distinguishing it from more conventional crime dramas. Brooke's long-running role in the series has become one of the defining parts of her career in recent years.

Further details about the new series and Brooke's character were not specified in the available excerpt of the interview.
