The American Ruling Class is a 2005 dramatic documentary film written by Lewis H. Lapham and directed by John Kirby that "explores our country’s most taboo topic: class, power and privilege in our nominally democratic republic." It seeks to answer the question, "Does America have a ruling class?" Its producers consider it the first "dramatic-documentary-musical." A rough-cut of the film was shown at the 2005 Tribeca Film Festival, the final version of the film was shown on the Sundance Channel in July 2007, and it had its theatrical premiere at the Brooklyn Academy of Music in April 2008.
