Star actors, maybe (6)
I believe the answer is:
castor
'star' is the definition.
(Castor is an example)
'actors maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'actors' anagrammed gives 'CASTOR'.
(Other definitions for castor that I've seen before include "Small swivelling wheel on a furniture leg" , "Powdered sugar" , "One star" , "Trolley wheel" , "hat" .)
