You and I back film (7)

I believe the answer is:

western

'film' is the definition.
(Western is an example)

'you and i back' is the wordplay.
'you and i' becomes 'we'.
'back' becomes 'stern' (I've seen this before).
'we'+'stern'='WESTERN'

(Other definitions for western that I've seen before include "Cowboy film of occidental origin" , "Cowboys and Indians movie" , "Type of film or music" , "Old film genre, horse opera" , "The Occident" .)

I've seen this clue in The Times and The Guardian.
