Get away on time for film (5)
I believe the answer is:
shoot
'for film' is the definition.
(synonyms)
'get away on time' is the wordplay.
'get away' becomes 'shoo' (I've seen this before).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'time' becomes 't' (abbreviation).
'shoo'+'t'='SHOOT'
(Other definitions for shoot that I've seen before include "Fire - new growth" , "Film; move rapidly" , "big game expedition?" , "Pump full of lead" , "modelling session" .)
