Stagger from film finishing early (4)
I believe the answer is:
rock
'stagger' is the definition.
(thesaurus)
'film finishing early' is the wordplay.
'film' becomes 'rocky' (I've seen this before).
'finishing early' means to remove the last letter.
'rocky' with its final letter removed is 'ROCK'.
'from' is the link.
(Other definitions for rock that I've seen before include "Lull (baby); 50s pop" , "Big stone - music" , "Pop; precious stone" , "Brighton sweet?" , "Shake; boulder" .)
