Actor ____ Robbins (3)
I believe the answer is:
tim
'actor robbins' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tim that I've seen before include "Tiny chap" , "Tiny . . . is a loveable Dickens boy" , "-- Brooke-Taylor, comic" , "Sir -- Rice, lyricist" , "Little fellow" .)
