Putney Swope

Putney Swope, a 1969 satirical comedy film written and directed by Robert Downey, Sr. and starring Arnold Johnson as Swope, is a comedy satirizing the advertising world, the portrayal of race in Hollywood films, the white power structure, and the nature of corporate corruption.

Renaming the business Truth and Soul, Inc., Swope replaces all but one of the white employees and insists they no longer accept business from companies that produce alcohol, war toys, or tobacco. The success of the business draws unwanted attention from the United States government, which considers it a threat to the national security.In an interview on the DVD version of the film, Downey states that Arnold Johnson had great difficulty memorizing and saying his lines during the film shoot. Downey says he didnt worry about it because he had developed a plan to dub in his own voice to replace Johnsons line readings. ........
