Great actor resting, by the sound of it? (4)
I believe the answer is:
idol
'great actor' is the definition.
'idol' can be an answer for 'actor' (idol is a kind of actor). I am unsure of the 'great' bit.
'resting by the sound of it?' is the wordplay.
'resting' becomes 'idle' (I've seen this in another clue).
'by the sound of it?' shows a homophone (sound like).
'idle' is a homophone of 'IDOL'.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "A matinee -- is a handsome actor" , "Favourite" , "Pop - - (TV)" , "One much admired" , "Worshipped image; lido (anag.)" .)
