His father left the family soon after Strong's birth, and Strong was brought up by his mother while she worked as an au pair. He later said, "The home I grew up in was a flat in Myddelton Square in London's Islington, a beautiful Georgian square with a huge church in the middle. We moved around a lot when I was young. I remember flats in Walthamstow, Clapton, Stoke Newington, and Edmonton." He said in 2008 that he was inspired to become an actor by watching French actor Alain Delon, but clarified in 2019 that he did not actually consider acting as a career until he was older. When Strong was little, his mother legally changed his name to help him fit in with his English peers. He was baptised a Catholic. He attended Wymondham College in Morley, Norfolk, where he sang in two punk bands, the Electric Hoax and Private Party—the latter's name based on the idea that people wouldn't attend their shows, thinking they were private parties. Strong had ambitions to become a lawyer but returned to London after one year of studying German law at the Ludwig Maximilian University of Munich. He subsequently studied English and drama at Royal Holloway, University of London before attending the Bristol Old Vic Theatre School. Career Strong appeared in two Prime Suspect serials for ITV as Inspector (later Detective Chief Superintendent) Larry Hall, in Prime Suspect 3 (1993) and Prime Suspect 6 (2003). He also had starring roles in two BBC Two drama serials, Our Friends in the North (1996) and The Long Firm (2004), earning a BAFTA nomination for the latter. He also played the villainous Colonel Brand
