Film star playing Ronald Borman (6,6)
I believe the answer is:
marlon brando
'film star' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'playing ronald borman' is the wordplay.
'playing' indicates an anagram.
'ronald'+'borman'='ronaldborman'
'ronaldborman' anagrammed gives 'MARLON BRANDO'.
Can you help me to learn more?
(Other definitions for marlon brando that I've seen before include "Best Actor Oscar winner 1972, for "The Godfather"" , "US actor, star of "On the Waterfront" (1954)" .)
