Actor's represented Cuban leader (6)
I believe the answer is:
'cuban leader' is the definition.
(I've seen this before)
'actor's represented' is the wordplay.
'represented' indicates anagramming the letters.
'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" .)
