 "Terrible Teddy, the Grizzly King" was inspired by political cartoons that originally ran in William Randolph Hearst's "New York Journal".These cartoons depicted Roosevelt as a macho hunting enthusiast with a strong taste for publicity, killing a mountain lion in Colorado while the press took in the event.The film is based on 1901 "New York Journal" comics panels that ran on February 4 (first shot) and 18th (second shot) very closely.
