Big movie - not entirely dramatic, I perceive, after being upset (4)
I believe the answer is:
epic
'big movie' is the definition.
'epic' can be an answer for 'movie' (I have seen 'Great movie' mean 'epic' so perhaps 'movie' could also mean 'epic'). I am not certain of the 'big' bit.
'not entirely dramatic i perceive after being upset' is the wordplay.
'not entirely' says the answer is hidden in the clue.
'being upset' says the letters should be written in reverse.
'cipe' is hidden in the letters of 'dramatic i perceive after'.
'cipe' written backwards gives 'EPIC'.
Can you help me to learn more?
(Other definitions for epic that I've seen before include "Ben Hur, say" , "Long literary work about great events" , "Heroic narrative verse" , "eg The Iliad" , "great film" .)
