Walker decided to retire from filmmaking after his last film in order to focus on buying and restoring cinemas.
[8] Malcolm McLaren hired Walker to direct a documentary on The Sex Pistols entitled A Star Is Dead.
Walker's work was reviled and condemned by some contemporary critics, while others were surprised to find relatively sophisticated subtexts in what were made and marketed as commercial exploitation films.
Although Walker's movies have never undergone a critical reappraisal in the same way as Hammer films or his American contemporaries Tobe Hooper and Wes Craven, the release in 2005 of a DVD boxed set of five of his films was greeted with some good notices in the British national press.
