BBC One's hit show The Responder has its finale tonight, with viewers keen to see how the tense police drama concludes.
Its main star, Martin Freeman, has won praise and five-star reviews for his portrayal of police officer Chris Carson, the perpetually angry, stressed officer on the edge who has been demoted to constable. His job responding to emergency calls has left him feeling constantly exhausted, as has his relationship with drug dealer Carl and addict Casey.
Freeman has long been known for his roles as Bilbo Baggins in The Hobbit trilogy, Dr John Watson in the BBC drama Sherlock and as Tim in Ricky Gervais' classic series The Office.
