Discarded actors? (4)
I believe the answer is:
cast
This clue is a double definition.
'discarded' is the first definition.
(I've seen this before)
'actors?' is the second definition.
(group of actors)
(Other definitions for cast that I've seen before include "Shed - actors" , "Throw off; select (actor)" , "Select actors for play or film" , "characters together" , "Team of actors in a play" .)
