Trial in camera? (6,4)
I believe the answer is:
screen test
This clue could be a double definition.
'trial' is the first definition.
(I know that screen test is a type of audition)
'camera?' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'in' is the link.
Can you help me to learn more?
(Other definitions for screen test that I've seen before include "Film actor trial" , "in which player is evaluated" , "Film audition" , "What might precede filming" , "trial for players" .)
