In 1937, Corrigan was on a hunting trip with Clark Gable when he had an idea to purchase land in Simi Valley, California and use it as a Western-themed ranch similar to Iverson Movie Ranch. He paid a $1,000 down payment, then a thousand dollars a month until the $11,354 price was paid. He developed this into Corriganville, a location used for many Western films and TV shows. The location featured many different types of terrain for producers such as lakes, mountains, and caves. Not merely set fronts, Corriganville contained actual buildings where film crews could live and store their equipment to save the time and expense of daily travel from studios to an outdoor location.
