Horse Breaking Montage … Mike (doubling Henry Thomas) and Richard (doubling Matt Damon) rode and “broke” some 20 horses in this montage which was shot over three days: one day for roping, two days for breaking. The pair roped the horses in the corral, snugged them to posts, saddled and blindfolded them and rode the bucking horses. It required extensive knowledge of riding and roping unbroken horses.
