In movies, they may get cars to crash! (6)
I believe the answer is:
actors
'in movies they' is the definition.
The definition suggests a plural noun which matches the answer.
'get cars to crash' is the wordplay.
'get' is a charade indicator (letters next to each other).
'crash' is an anagram indicator.
'cars'+'to' is 'carsto'.
'carsto' is an anagram of 'ACTORS'.
'may' is the link.
Can you help me to learn more?
(Other definitions for actors that I've seen before include "Thespians" , "Theatrical performers" , "Cast" , "Luvvies" , "They 23 down" .)
