Pixar film set in Mexico (4)
I believe the answer is:
coco
'pixar film set in mexico' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for coco that I've seen before include "French fashion designer, who branched into perfume etc" , "address for Chanel" , "Famous clown" , "Gabrielle Bonheur Chanel" , "'... the Clown, ... Chanel (4)'" .)
