“A man ought to do what he thinks is best.” —John Wayne as Hondo Lane, Hondo (1953) The dog that played Sam in the film was named Pal and he was the original screen Lassie. In this movie, he is supposed to be vicious and ill-tempered, but the temperatures during filming were so hot, he simply panted instead of snarling when on-camera. To overcome this, he was kept in a special air-conditioned crate while on set and was only brought out for his shots. He sure convinced us he was not to be tangled
