Shot lengthy film, avoiding Spain (3)
I believe the answer is:
pic
'shot' is the definition.
(short for picture)
'lengthy film avoiding spain' is the wordplay.
'lengthy film' becomes 'epic' (epic film).
'avoiding' suggests deleting specific letters.
'spain' becomes 'e' (abbreviation for Espana).
'epic' with 'e' taken away is 'PIC'.
(Other definitions for pic that I've seen before include "Photo (colloq.)" , "Image (abbr)" , "Snapshot" , "Photograph (colloq.)" , "Photo (informal)" .)
