Bogart raged endlessly about leading actress (5,5)
I believe the answer is:
greta garbo
'leading actress' is the definition.
'bogart raged endlessly about' is the wordplay.
'endlessly' means to remove the last letter.
'about' indicates an anagram.
'bogart'+'raged'='bogartraged'
'bogartraged' with its last letter taken away is 'bogartrage'.
'bogartrage' is an anagram of 'GRETA GARBO'.
(Other definitions for greta garbo that I've seen before include "See actress" , "Old actress" .)
