Sidney Poitier leads the way in one of the first black action films ever, in some ways (but not all) a precursor to the 'blaxploitation' genre that was to follow beginning with Super Fly, Shaft et al.
A black Philadelphia detective becomes involved in a murder case in a small, bigoted southern town, much to the chagrin of the local, redneck police chief. An excellent production, adapted by Stirling Silliphant from John Ball's novel. Academy Award Nominations: 7, including Best Director.
What a film!
