Very much game for movie set in N. Dakota (5)
I believe the answer is:
fargo
'movie set in n dakota' is the definition.
'very much game' is the wordplay.
'very much' becomes 'far' (I've seen this in another clue).
'game' becomes 'go game' (go is a kind of game).
'far'+'go'='FARGO'
'for' acts as a link.
(Other definitions for fargo that I've seen before include "He and Wells founded US stagecoach company" , "Partner of Wells in US transport company" , "Wells --, stagecoach service" .)
