Famous actor figures in a new role (7)
I believe the answer is:
'famous actor' is the definition.
(Sir Laurence Olivier)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for olivier that I've seen before include "Laurence (Lord) ---, actor" , "He starred in classic films of Hamlet and Henry V" , "First actor to become a life peer" , "Laurence -, English actor and director" , "Great English actor playing rilievo" .)
