The Day of the Wolves was the first movie to be made on location in the new town of Lake Havasu City, Arizona. In late 1970, the McCulloch Corporation was actively promoting Lake Havasu, and especially the old London Bridge, which was being reconstructed in Lake Havasu at enormous expense and effort. To this end, the McCulloch Corporation flew film producers to Lake Havasu offered production film support, which Grofe took advantage of. This was the last feature film made by actress Martha Hyer.
