Pleasure to see Sidney Poitier and Harry Belafonte together in a western no less!
It strikes me that it would make a decent double-feature with The Cheyenne Social Club. By the 1970s, both westerns feel like relics of the earlier decade, but there's something pleasing about watching old compadres like Poitier and Belafonte or Stewart and Fonda chew the fat in the saddle together.
Although to be fair, Buck and the Preacher, between its leads, allegory to Civil Rights, and certainly a couple of rip-roaring shootouts is a more intriguing package. Poitier's directorial debut is worth consideration.
