Advertised Barbour motorcycle clothing aboard a Hesketh motorcycle.
An avid fan of Chelsea Football Club, London. Ironically, as Terry McCann, his character in Minder, he had to play a fan of Fulham football Club who are Chelsea's local rivals from London.
Grandfather to Jack Higginson (b. 2011) via daughter Hannah Waterman and her partner Huw Higginson.
Had a top ten hit in the U.K. with the song "I Could Be So Good for You" in October 1980.
His duet with "Minder" (1979) co-star George Cole, "What Are We Gonna Get 'Er Indoors?", reached the number 21 position on the UK chart in 1983.
His elder brother is boxer Peter Waterman.
Mercilessly lampooned on "Little Britain" (2003) as a midget whose keeps losing contracts by insisting on singing the theme song for the proposed show. Waterman got his revenge by making a surprise appearance in the charity presentation Comic Relief Does Little Britain: Live (2007) (V), interrupting Walliams and Lucas performing a version of their Dennis Waterman sketch. During his appearance, Waterman gets to complain that he does not have a high voice, is not "a midget," and does not sing or write the theme tune of all his shows. To apologize, Walliams and Lucas perform one of Waterman's songs with him.
Once filmed an episode of Minder at Stamford Bridge, home of his Chelsea F.C. Unfortunately the story line meant that he was actually thrown out of the stadium!
Two daughters with Patricia Maynard: Hannah Waterman (born 1975) and Julia Waterman (born 1979).
