During his tenure as the Doctor, Pertwee appeared in the Amicus horror compendium "The House That Dripped Blood" (1971), which was filmed in the summer of 1970 between his first and second "Doctor Who" seasons. Pertwee played the lead in the last segment of the film as Paul Henderson, an arrogant horror film star who meets his doom thanks to a genuine vampire cloak. In 1973 Pertwee endorsed the Co-op's "Baking Your Cake and Eating It", a recipe book written by Sarah Charles. It has been given the unofficial title of "The Jon Pertwee Recipe Book".
