I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Scream and Scream Again Movie plot: A London jogger suddenly collapses on the sidewalk and awakens in a hospital where he finds that his right leg has been amputated. Shortly thereafter, his left leg is amputed, followed by the amputation of both arms. He can get no information from his zombielike nurse. Meanwhile, somewhere in a Gestapo-like country in Eastern Europe, military agent Konratz [Marshall Jones] lets slip to his superior, Captain Salis [Peter Sallis], that he knows about the top-secret K-718. Because K-718 is classified information supposed to be known only to Salis and his superior, Major Benedek [Peter Cushing], Salis tries to contact Benedek, but Konratz kills Salis before the call goes through. With Salis dead, Konratz moves up into his position. When Benedek decides to dismiss Konratz from duty because his methods of interrogation are too extreme and will not reflect nicely upon their military regime, Konratz kills Benedek and moves into Benedek's position.London Detective Superintendent Bellaver [Alfred Marks] also has his hands full with a series of killings that have been dubbed the "vampire murders." Girls are being found with their throats slashed, puncture wounds on their arms, and drained of blood. The first was Eileen Stevens, an employee of esteemed research scientist, Doctor Browning [Vincent Price], but Browning has no idea who would want to murder her. When another girl turns up dead and Bellaver realizes that they were both picked up at The Busted Pot (a disco club), policewoman Sylvia [Judy Huxtable] goes undercover (with a homing device planted in her shoe) to see if she can get picked up by the vampire. She is successful, and she and the vampire Keith [Michael Gothard] drive to a secluded field where he attempts to drink her blood. Keith is interrupted by the police but manages to best them all and get away. Fortunately, Sylvia's shoe is still in Keith's car, so the police tail him. Keith drives to a chalk quarry where the police are astounded to see him running up the almost sheer cliff face...until he slips... My question: Who does Peter Cushing play?
A:
Major Heinrich Benedek
