Biography from the Wikipedia article, licensed under CC-BY-SA

Collins was best known for his role in the long running BBC police series Juliet Bravo, where he played Sergeant George Parrish throughout the six year run of the show. He also appeared in Play for Today, When the Boat Comes in and the comedy series Bread.

Collins retired at the age of 60 after being diagnosed with lung cancer and undergoing an operation which involved removing a lung. In the 1990's he joined 52 other claimants in a Ј17million lawsuit against cigarette giants Gallaher and Imperial Tobacco arguing that the companies had been negligent in not reducing the tar content in their cigarettes between 1957 and 1971 once it became obvious that smoking caused lung cancer.

Although the case was dropped in March 1999 Collins retained his anti smoking stance until his death. His widow Helen Collins paid tribute to her husband's bravery in the face of his illness. "He was content in his life but also stoic during the bad times. He became very anti-smoking but he lived through his illness as best he could. Even in his last week he was still getting Juliet Bravo fan mail which he found amusing. He loved the theatre and really enjoyed his career, but without being pretentious or boastful." 

Noel Collins died on 15 August after losing his long battle with cancer.
