The Walt Disney Family are releasing a new documentary to cinemas in the United States on September 11 titled Walt & El Grupo
It is about Walt's trip to South America in 1941 which was sponsored by the US Government and was designed as a goodwill tour to promote US values at a time when German-led fascism was in danger of taking off in the continent. The US Government obviously didn't want a continent of Nazis on their doorstep - so it was Walt to the rescue!

They are tying the release date of this film with the opening of the Walt Disney Family Museum in San Francisco.
