Film footage randy don destroyed (3,3,9)

I believe the answer is:

dog day afternoon

'film' is the definition.
(1975 film)

'footage randy don destroyed' is the wordplay.
'destroyed' is an anagram indicator.
'footage'+'randy'+'don'='footagerandydon'
'footagerandydon' is an anagram of 'DOG DAY AFTERNOON'.

I've seen this clue in The Telegraph.
