Wolf Dog (1958) is a Western movie, directed and produced by Sam Newfield and released by Regal Films. In August 1957, Newfield and a camera crew filmed the movie in and around Markdale, Ontario, near Owen Sound, Ontario, Canada. The movie co-starred Hollywood actors Jim Davis, Allison Hayes and John Hart along with Canadian actors Austin Willis and Tony Brown. Several locals were offered a chance to be unpaid "extras". Among those were Paul Hutton, Jerry Bartley, Constable Clarence Bowins, David Jackson, Officer Jack Johnston, Ron Wyvill, Don Wyvill. While not an artistic or commercial success, the film is noteworthy in that it was created almost 40 years before Telefilm Canada and federal government subsidies enabled big-name movies to be filmed in Canadian locales. Markdale residents were delighted to have Hollywood make a film in their town. It was hoped a film set in "The Great North Country" would be a crossover hit in the U.S. and the Commonwealth, both lucrative movie markets. For reasons unknown, the film disappeared from the public eye for almost 50 years.
