Who is Sinéad Keenan, and what’s she been in before?

Sinéad Keenan is an actress, known for playing a werewolf in BBC Three’s supernatural drama Being Human.

Irish viewers will probably know her best for playing Farrah Phelan in Fair City.

After quitting her role as Nina in Being Human, Sinéad moved on to grittier roles.

Her role as Melanie Jones in Little Boy Blue earned her a well-deserved BAFTA nomination.

The ITV series dramatised the murder of 11-year-old Rhys Jones in Croxteth, Liverpool in 2007.

Recently, Sinéad popped up as Aideen O’Shea in Derry Girls, and DI Paula Cassidy in Showtrial.

She also took on the role of Theresa Ryan in another hard-hitting drama, Three Families.

Three Families told the story of real-life families and how they were each affected by Northern Ireland’s restrictive abortion law before it was lifted in 2019.

Sinéad has also played Addams in David Tennant‘s final episodes of Doctor Who (before he came back!), Patricia in My Left Nut, Roz in Deep Water, and Dr. Bartholomew in Porters.

Her latest role sees her replace DCI Cassie Stuart in Unforgotten.

Sinéad Keenan takes the female lead as DCI Jess James, alongside Sanjeev Bhaskar’s DI Sunil ‘Sunny’ Khan.

Dublin-born Sinéad began filming her new role earlier in 2022.

Actress Sinéad is from Dublin, Ireland.

She attended University College Dublin, graduating with a degree in Sociology and History.

But, as she got older, she realised that she actually just wanted to play the part of the lawyer, not be one!
