“I don’t understand it, but I like it,” Rugoff told Downey. Aided by an extraordinary marketing and ad campaign still remembered today, “Putney Swope” became the rare American independent film to be treated like a top foreign-language art film. Among Downey Sr.’s early micro-budget directorial efforts were “Balls Bluff” (1961), “Babo 73” (1964), “Chafed Elbows” (1966), and “No More Excuses” (1968). The director was also an actor, with performing credits in films such as “Boogie Nights” (1997), “Magnolia” (1999), and “The Family Man” (2000), plus many more titles. As a director, his final work was on the 2005 documentary “Rittenhouse Square.”

Downey Sr. also worked with his son, Robert Downey Jr., on a number of films, such as the 1997 romantic comedy “Hugo Pool,” written and directed by the Downey Sr. and co-starring his son opposite Alyssa Milano and Patrick Dempsey. Yet “Putney Swope” remains Downey Sr.’s masterpiece and was chosen for the National Film Registry by the Library of Congress in 2016. “Searching for Mr. Rugoff” opens on August 13. Initial dates include the Paris Theater (New York), Royal (Los Angeles), and Coolidge Corner (Boston). Check out the exclusive clip, available only on IndieWire, below.
