Set of actors (4)
I believe the answer is:
cast
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">set of actors</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cast that I've seen before include "Troupe" , "Shy - group of actors" , "Character" , "Discard; actors (in play)" , "Mould; actors in a play" .)
