ITV's new thriller, Our House, boasts an impressive cast list that includes stars from Line of Duty, Downton Abbey and The Fall. One of the most recognisable actors on the show is Rupert Penry-Jones, who drama fans will recognise as DI Joseph Chandler in Whitechapel and Adam Carter in Spooks.
While Rupert is one of the UK's most well-known TV actors, viewers may be surprised to know that he isn't the only star in his family as he shares a familial connection with Bridgerton actress Polly Walker.

Rupert's brother, fellow actor Laurence Penry-Jones, is married to Polly, making the Our House star her brother-in-law.
Viewers will know Polly for her role as the ambitious Portia Featherington in the Bridgerton series, who is determined to make beneficial matches for her three daughters. She also played Gill Biggeloe in Line of Duty.
Polly and Laurence tied the knot in 2008, one year after Rupert married his own wife, Dervla Kirwan, who is also an actress.

Dervla recently appeared in Harlan Coben's The Stranger on Netflix, where she played the suspicious Corrine Price, wife to Richard Armitage's Adam.
