This is one of the best films not currently available on DVD, although it does pop up on Youtube from time to time. Sidney Furie, of Ipcress File fame was originally to direct, but dropped out due to ill health. In fairness there are only a couple of shots that look like the handiwork of Furie, so I would not seriously claim that he is the reason it is so unexpectedly amazing.
This is one of those films that is just a non-stop thrill ride from the moment the former cop's daughter is mistaken for a wealthy business man's daughter and kidnapped. There are two absolutely amazing sequences, a pedal to the metal chase through New York that looks incredibly real, and a crazed cop chasing our hero with a shot gun, shooting up shop windows as shocked bystanders try to jump out of the way. The real star of the show is the pre-cleaned up New York, looking like a bombed out Dresden with pimps, drug dealers and all manner of wackos.
It does lose momentum slightly by the end, but this can sit alongside films like Dirty Harry and the Warriors as a tough bleak urban thriller.
This film calls out for a reissue or remake, go on punk ...
