Arthur Penn, the director of "Bonnie and Clyde," The Miracle Worker" and "Alice's Restaurant," died Tuesday in New York a day after turning 88. He received Oscar nominations for the first of those two films, and also won a Tony for directing "The Miracle Worker" on Broadway. His work in 1967's "Bonnie and Clyde" was a "revolutionary treatment of sex and violence...[that] transformed the American film industry," says the New York Times obit:
A pioneering director of live television drama in the 1950s and a Broadway powerhouse in the 1960s, Mr. Penn developed an intimate, spontaneous and physically oriented method of directing actors that allowed their work to register across a range of mediums.
In 1957, he directed William Gibson’s television play “The Miracle Worker” for the CBS series “Playhouse 90” and earned Emmy nominations for himself, his writer and his star, Teresa Wright. In 1959, he restaged “The Miracle Worker” for Broadway and won Tony Awards for himself, his writer and his star, Anne Bancroft. And in 1962, he directed the film version of Mr. Gibson’s text, which won the best actress Oscar for Bancroft and the best supporting actress Oscar for her co-star, Patty Duke, as well as earning nominations for writing and directing.
Mr. Penn’s direction may also have changed the course of American history. He advised Senator John F. Kennedy during his watershed television debates with Richard M. Nixon in 1960 (and directed the broadcast of the third debate). Mr. Penn’s instructions to Kennedy — to look directly into the lens of the camera and keep his responses brief and pithy — helped give the candidate an aura of confidence and calm that created a vivid contrast to his more experienced but less telegenic Republican rival.
