While real-life outlaws Butch Cassidy and the Sundance Kid were closely bonded, actor Paul Newman revealed that at the time filming, he had some resentments over the young Robert Redford.

A real testament to their acting skills, Newman, playing Robert LeRoy Parker or “Butch Cassidy,” and Redford as Harry Longabaugh “Sundance Kid,” were persuasive in their portrayals of the Wild West buddies, notorious criminals who were on the run from the law after a string of bank and train robberies.

The 1969 movie about the real-life outlaws won four Oscars and holds up as one of the greatest Westerns ever made. Four years later, the stars–both handsome heartthrobs–partnered up again for another caper film, The Sting (1973).
