Michael Powell is best known for his work of the ’40s and ’50s—sensuous in its way but very buttoned-up. Then the ’60s arrived, and he made the audacious Peeping Tom, which openly considered eros, if only to equate it with murder. It was the outraged reaction to that movie that drove Powell to Australia, where he made his most openly erotic film, Age of Consent. The 1969 drama is the tale of a creatively exhausted painter who flees New York for his native Queensland, where he’s reinvigorated by Cora, a free-spirited and often naked teenager. The film debut of Helen Mirren (then actually in her early 20s) as Cora could have become an icon of the sexual revolution. But the resulting movie, a hit Down Under, was trimmed of sex and nudity before being released in the United States and United Kingdom, where it flopped. The film shows at 7 p.m. at the Library of Congress’ Pickford Theater, 101 Independence Ave. SE. Free. (202) 707-5677.
