European movie, very long (4)
I believe the answer is:
epic
'very long' is the definition.
(I've seen this before)
'european movie' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'movie' becomes 'pic' (abbreviation for picture**).
'e'+'pic'='EPIC'
(Other definitions for epic that I've seen before include "Blown up" , "Nonsense, rubbish" , "Guardian (body, beast)" , "On a grand scale, like heroic poem" , "Large in scale" .)
