No time at all to get wind of wild film idea (8)
I believe the answer is:
scenario
'film idea' is the definition.
(scenario can mean an outline or plan for a film)
I can't explain the remainder of the clue.
(Other definitions for scenario that I've seen before include "Imagined sequence" , "Film plot outline" , "expected sequence of events" , "Outlines of drama" , "Dramatic situation" .)
