Get rid of actors (4)
I believe the answer is:
cast
I believe this is a double definition.
'get rid of' is the first definition.
(as in casting away)
'actors' is the second definition.
(group of actors)
(Other definitions for cast that I've seen before include "Throw out line for fish" , "Play's actors" , "Pot" , "Team of actors in a play" , "Dramatis personae" .)
