Act divisions (6)
I believe the answer is:
scenes
'act divisions' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scenes that I've seen before include "Dramatic divisions" , "Subdivisions in theatre" , "Subdivisions of play acts" , "displays of emotion" , "Excerpts from a film - or aggressive outbursts" .)
