Silent actor excited Dolly (5)
I believe the answer is:
lloyd
'silent actor' is the definition.
(Harold Lloyd)
'excited dolly' is the wordplay.
'excited' is an anagram indicator.
'dolly' is an anagram of 'LLOYD'.
(Other definitions for lloyd that I've seen before include "Bridges perhaps" , "Harold --; -- George" , "Marie -, nineteenth to twentieth century English music-hall entertainer" , "David - George, British PM nineteen sixteen to nineteen twenty two" , "Frank -- Wright, US architect" .)
