Films provided to occupy relative (7)
I believe the answer is:
silents
'films' is the definition.
(I have seen 'Soundless films ' mean 'silents' so perhaps 'films' could also mean 'silents')
'provided to occupy relative' is the wordplay.
'provided' becomes 'lent' (I've seen this in another clue).
'to occupy' means one lot of letters goes inside another (inserted letters occupy or enter the word).
'relative' becomes 'sis' (short for sister).
'lent' going inside 'sis' is 'SILENTS'.
(Another definition for silents that I've seen is " Soundless films".)
