Top-billing goes to Anthony Newlands in a relatively brief role, but it's Glynn Houston who carries the film in the title role as the cop who goes it alone against a gang of violent desperados whose ranks include Michael Caine.
Although now recalled solely because Caine is in it (eleventh in the cast list but already eye-catching because of his height, but deprived of most of his lines during shooting due to his dire attempt at an Irish accent), it's actually chock-a-block with familiar faces right down to a brief appearance by Wanda Ventham as a waitress.
Even without the distinction of having Caine in it this is definitely one of the better Merton Park Edgar Wallace's thanks to Roger Marshall's sharp script and nifty direction by Gordon Flemyng (whose staging of the scene in which Houston interviews Neil McCarthy over a snooker table is worthy of Bergman). Almost everybody is of course dressed effortlessly immaculately as befits the era of JFK and Malcolm X; while Nadja Regin in one outdoor scene models a chic leather suit that probably cost more than the rest of the film's budget combined.
