Laurence —, English actor (7)
I believe the answer is:
olivier
(Other definitions for olivier that I've seen before include "English actor best known for his Shakespearean roles" , "Sir Laurence -, English actor (Hamlet, nineteen fourty eight)" , "- Messiaen, Twentieth century French composer" , "O! Virile (anag) - English actor, d. 1989" , "Sir Laurence -, twentieth century English actor" .)
