Although it is set in the ghetto, features Antonio Fargas in proto-Huggy Bear mode and opens with a classy soul/funk title track by Bobby Womack and Peace (made famous by Quentin Tarantino with Jackie Brown), Across 110th Street is no Blaxsploitation flick.
Instead we have an early black cop/white cop thriller pitched halfway between Serpico and Shaft, based on a novel by Wally Ferris, with Anthony Quinn (also credited as Executive Producer) as a corrupt, racist old-timer teaming up with Yaphet Kotto's squeaky-clean rookie on a cop-killer case. Its a little pale and occasionally clumsy by today's standards, but still a gritty, violent tale of gangland violence, racism and poverty.
