In reality, Munro's record-breaking run at Bonneville came after several separate visits to the US, beginning in 1956. This was demonstrated, for instance, by a letter published in the May 1957 edition of "Popular Mechanics" (p. 6), which referred to 'H. A. "Dad" Munro' and his 1920 Indian Scout. The visit to Bonneville shown in the film was a composite of several made by Munro. In 1962 he set a record of 178.971 mph at Bonneville. His fastest complete run there was 190.07 mph. While Munro did reach 205.67 mph on an uncompleted run, on which he crashed, he never set a record of 201 mph at Bonneville (as the film suggests).
