Stanley Baker in
Hell Is a City

Important in the evolution of the police procedural, Hell Is a City (U.S. book title: Somewhere in This City) was written by ex-police officer Maurice Procter as the first of his Granchester series. Directed by Val Guest (The Quatermass Xperiment), the film features the always interesting Stanley Baker, Billie Whitelaw, and Donald Pleasence. Baker's Inspector Harry Martineau hunts for an prison escapee in gritty Manchester (filmed on location).
