Film icon Marlene (8)
I believe the answer is:
dietrich
(Other definitions for dietrich that I've seen before include "Marlene . . . . . . . ., late German star of stage and screen" , "Marlene . . . . . . . . was a famous film star" , "Former actress" , "Marlene ..., German-born film star" , "Old German film star had a cider hit" .)
