Actor John ____ (5)
I believe the answer is:
wayne
'actor john' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for wayne that I've seen before include "John --, film star" , "- - 's World (film)" , "Fort --, city in Indiana" , "See seventeen accross" , "John ....., later hero of western films" .)
