Nonstudio film (5)
I believe the answer is:
indie
'nonstudio film' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for indie that I've seen before include "Non-affiliated record label or pop group (colloq.)" , "Non-mainstream film company" , "Non-mainstream record label" , "Not a mainstream group" , "Type of music" .)
