Roger Michael Watkins (September 17, 1948 - March 6, 2007) was a film director best known for the notorious 1970s grindhouse movie Last House on Dead End Street. He also directed several porn films. He worked with famous porn actors like Jamie Gillis and Vanessa del Rio.
The Internet Movie Database lists a number of Watkins' aliases (see the information box at right), most of which he seems to have used in Last House on Dead End Street to conceal the fact that he worked in several technical capacities on that film - director, actor, cameraman, etc.
