Actor's represented Cuban leader (6)
I believe the answer is:
castro
'cuban leader' is the definition.
(I've seen this in another clue)
'actor's represented' is the wordplay.
'represented' indicates an anagram.
'actors' with letters rearranged gives 'CASTRO'.
(Other definitions for castro that I've seen before include "Latin American dictator" , "Cuban co-star" , "Fidel ......, Cuban chief" , "He's late" , "Latin-American presidential co-star" .)
