Once upon a time, MGM launched a big spectacle Western remake with the top star Glenn Ford and the bright import Maria Schell — and then second-guessed the whole production, cutting back on everything so severely that director Anthony Mann ankled the set for Spain and El Cid. The storytelling is a mess — after starting big, the show soon falls into pieces. But many of individual scenes and set pieces are exemplary, especially Mann’s re-run of the Oklahoma Land Rush, staged in Arizona and augmented by classy special effects. The large cast rounds up some big talent — Mercedes McCambridge, Russ Tamblyn — to tell Edna Ferber’s multi-generational story about ambition, intolerance and dreams of glory on the frontier. With Anne Baxter, Arthur O’Connell, Russ Tamblyn, Mercedes McCambridge, Vic Morrow, Charles McGraw, Harry Morgan, David Opatoshu, Aline MacMahon, and a whole lotta horses. On Blu-ray from The Warner Archive Collection.
