US cop story, not right to reboot film (9)
I believe the answer is:
octopussy
'film' is the definition.
(I've seen this before)
'us cop story not right to reboot' is the wordplay.
'not' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'to reboot' indicates an anagram.
'us'+'cop'+'story'='uscopstory'
'uscopstory' with 'r' taken away is 'uscopstoy'.
'uscopstoy' is an anagram of 'OCTOPUSSY'.
(Other definitions for octopussy that I've seen before include "Bond film with Roger Moore (many-tentacled cat?)" , "1983 James Bond film" .)
