Not from a big studio (5)
I believe the answer is:
indie
'not from a big studio' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for indie that I've seen before include "Autonomous film co." , "Pop music style" , "(Pop group) not affiliated with a major record company" , "not linked to major label" , "Not a mainstream group" .)
