Shakers film set in vineyards (6)
I believe the answer is:
cruets
'shakers' is the definition.
(a cruet is a salt or pepper shaker)
'film set in vineyards' is the wordplay.
'film' becomes 'ET' (E.T. the Extra-Terrestrial).
'set in' is an insertion indicator.
'vineyards' becomes 'crus' (cru is a French term for a vineyard).
'et' put into 'crus' is 'CRUETS'.
(Other definitions for cruets that I've seen before include "Table containers for salt and pepper" , "Truces about condiment containers" , "Salt and pepper are kept in them" .)
