Extra actors in cloudy conditions (8)
I believe the answer is:
overcast
'extra actors in cloudy conditions' is the definition.
I can't judge whether this defines the answer.
'extra actors' is the wordplay.
'extra' becomes 'over' (both can mean left over).
'actors' becomes 'cast' (group of actors).
'over'+'cast'='OVERCAST'
Can you help me to learn more?
(Other definitions for overcast that I've seen before include "(Of sky) cloudy, dull" , "Overacts, being gloomy" , "State of the sky when it is covered by clouds" , "The sky covered by dark clouds" , "State of a dark cloudy sky" .)
