Believes the end of a film (7)
I believe the answer is:
credits
'believes' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for credits that I've seen before include "Film's final sequence" , "balance sheet entries" , "moneys paid in" , "Believes" , "Last items of a film" .)
