Actor ____ Newman (4)
I believe the answer is:
paul
'actor newman' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for paul that I've seen before include "fellow" , "Beatle - singer with Peter and Mary" , "---23, C20 novelist" , "The first great Christian missionary" , "Some rob Peter to pay .." .)
