From their first pairing in ""Hamlet"" (1948) to their roles in ""House of the Long Shadows"" (1983), Christopher Lee and Peter Cushing have enjoyed the most successful collaboration in horror film history. Each of their 22 film collaborations is examined in detail, including plot synopses and critical commentary. A comprehensive filmography of their films together provides release date, running time, studio, production information and full cast and credits. The original research is supported by interviews with both Lee and Cushing, along with fellow performers and production personnel, such as Hazel Court, Robert Bloch, and Patrick Macnee.
