MGM films The first MGM "Lassie" film was planned as a low budget, black and white children's film. Pal was among 1,500 dogs who auditioned for the title role, but was rejected because he was male, his eyes were too big, his head too flat, and a white blaze ran down his forehead. A female prize-winning show collie was hired to play the title character. Weatherwax was hired to train the star, and Pal was hired as a stunt dog. During the course of filming, a decision was made to take advantage of a massive flooding of the San Joaquin River in central California in order to obtain some spectacular footage for the film. The female collie was still in training and refused to enter the raging waters created by the flood. Weatherwax was on the site with Pal and offered to have his dog perform in a five-stage shot in which Pal would swim the river, haul himself out, lie down without shaking the water off his coat, attempt to crawl while lying on his side and finally lie motionless, completely exhausted. Pal performed exceptionally well and the scene was completed in one take. Weatherwax said director Fred M. Wilcox was so impressed with Pal during the sequence that he had "tears in his eyes." In response, producers released the female collie and hired Pal in her stead, reshooting the first six weeks of the filming with Pal now portraying Lassie. Other sources say that the female collie was replaced because she began to shed excessively during shooting of the film in the summer. In any case, MGM executives were so impressed, they upgraded the production to an A film with full advertising support, top publicity and filming in Technicolor. Pal went through his paces with enthusiasm, rarely required multiple retakes, and did his own stunt work. Pal's success in Lassie Come Home in 1943 led to six more MGM films: Son of Lassie (a sequel to Lassie Come Home), Courage of Lassie, Hills of Home, The Sun Comes Up, Challenge to Lassie, and The Painted Hills. In his earlier years with MGM, Rudd Weatherwax was assisted by Frank Inn, who, for fourteen years, trained Lassies and later supplied animals for the 1954 Lassie television series. Following The Painted Hills in 1951, MGM executives felt Lassie had run her course and planned no future films featuring the character. MGM
