Atmospheric 1967 Norman Jewison thriller, and its weaker 1970 sequel from Gordon Douglas. The first, which won Oscars for Best Picture and Rod Steiger, is dryly observed, with Steiger's bigoted Southern sheriff warming to Sidney Poitier's detective as they solve a murder—a big anti-racism statement in its time. The second takes Poitier's Tibbs character to San Francisco, for no pressing reason.
