Warren Clarke (born 26th April, 1947) is a prolific British actor who is best known to television audiences as gruff police detective Andy Dalziel in the BBC series Dalziel And Pascoe, a role he has played from 1996 to the present day. He has played four different roles on Coronation Street, Barry in 1965, Kenny Pickup in 1966, Tim Jordan in 1968 and then Elsie Tanner's nephew Gary Bailey later in the same year. Just a few weeks before the first of these roles, he appeared in an episode of the Street spin-off Pardon the Expression, a series in which he made two appearances in two different roles in the following year.

Afterwards Warren had a large part in the controversial 1971 Stanley Kubrick film A Clockwork Orange, and went on to appear in The Onedin Line, Tinker, Tailor, Soldier, Spy, Minder and Blackadder the Third.
