on the “Rust” set Friday in exclusive photos obtained by The Post that also show, for the first time, Bianca Cline, the film’s new cinematographer, in action.The grey-bearded actor, 65, appeared in his Harland Rust costume, disheveled and bloodied as filming continued on the indie-Western in Montana.In one image, Baldwin stands casually, yet stoic, among his co-stars, dressed in a tattered blue shirt, suspenders, gray pants and dusty brown boots. When filming was at a standstill, he draped a red blanket over his shoulders.In other photographs, cameras appear to be rolling as Baldwin is hauled toward a noose by two men in cowboy hats, boots and gritty, trench-like jackets.
