Big English film (4)
I believe the answer is:
epic
'big' is the definition.
(similar in meaning)
'english film' is the wordplay.
'english' becomes 'e' (abbreviation).
'film' becomes 'pic' (short for picture).
'e'+'pic'='EPIC'
(Other definitions for epic that I've seen before include "Long story telling of a hero's deeds" , "Larger than life" , "Long, heroic story" , "great film" , "Long classic film" .)
