During the 27-minute super posse chase, Butch and Sundance dismount and separate from their lone horse, start scaling rocky terrain to evade their pursuers. Butch asks, "What if they don't follow the horse?". Sundance: "Don't worry, Butch, you'll think of something." Originally Butch retorts, "That's a load off my mind." That line was kept in the movie right through the mid-'70s until it was broadcast on network TV (1976). For some reason it was omitted and has remained absent through every TV, cable, video, laserdisc and previous DVD release. It was reinstated back into the 2006 "Ultimate Collector's Edition" DVD and viewers are treated to it for the first time in 30 years.

5.1 remix on the blu-ray releases has many new sound effects like gunshots, wind noises, insects, and even horse hooves hitting the ground. Only the US version of the blu-ray has the original mono mix as an alternative.

The UK release was cut, cut required to remove a scene of deliberate animal cruelty staged for the film (an animal being tripped using wires in a dangerous fashion), in order to obtain a PG classification. Cut required in accordance with BBFC Guidelines, policy and the Cinematograph Films (Animals) Act 1937. An uncut classification was not available.
