Actor - ultimate screen legend - receiving some R&R? (9)
I believe the answer is:
nicholson
'actor' is the definition.
(actor Jack Nicholson)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nicholson that I've seen before include "See 8" , "Jack -, US actor" , "Oscar winner 33" .)
