At least seven movies were filmed at the Stampede by 1950. The most profitable, the 1925 silent film "The Calgary Stampede", used footage from the rodeo and exposed people across North America to the event. Hollywood stars and foreign dignitaries were attracted to the Stampede; Bob Hope and Bing Crosby each served as parade marshals during the 1950s, while Queen Elizabeth II and Prince Philip made their first of two visits to the event as part of their 1959 tour of Canada. The Queen also opened the 1973 Stampede.
