Actor ____ Redford (6)
I believe the answer is:
robert
'actor redford' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for robert that I've seen before include "-- the Bruce" , "Founder of London's police force" , "---17 ac. 23, explorer" , "Butterfly" , "Boy's name" .)
