Filming celebrities " they're heavenly movers! (8,5)
I believe the answer is:
shooting stars
'heavenly movers' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'filming celebrities' is the wordplay.
'filming' becomes 'shooting' ('shoot' can be a synonym of 'film').
'celebrities' becomes 'stars' (I've seen this in other clues).
'shooting'+'stars'='SHOOTING STARS'
'they're' is the link.
Can you help me to learn more?
(Other definitions for shooting stars that I've seen before include "they have meteoric careers" , "Meteors" .)
