Trailers lent out between stars (12)
I believe the answer is:
interstellar
'between stars' is the definition.
(interstellar means between stars)
'trailers lent out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'trailers'+'lent'='trailerslent'
'trailerslent' anagrammed gives 'INTERSTELLAR'.
(Other definitions for interstellar that I've seen before include "Occurring between stars" , "In deep space" , "realm of Star Trek" .)
