Alfred —, director of film thrillers Sabotage and Saboteur (9)
I believe the answer is:
hitchcock
(Other definitions for hitchcock that I've seen before include "English thriller director, d. 1980" , "Alfred . . . . . . . . ., master director of cinema suspense (9)" , "See 8" , "Sir Alfred -, Eng. film director" , "Horrifying chap" .)
