Garbo of the silver screen (5)
I believe the answer is:
greta
'garbo of the silver screen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for greta that I've seen before include "Girl" , "- Garbo, Swed. actress" , ".....Garbo, who wanted to be alone" , "Miss Garbo" , "Female" .)
