If you park your TV dial (or its modern equivalent) on TCM tonight, you’ll be treated to a quadruple feature of some of the best films of the Seventies. The action begins with 1973’s Badlands, the first movie effort by director Terrence Malick. It’s as visually evocative and moodily poetic as his later films, but it also boasts especially dynamic performances from its two young, then unknown leads: Martin Sheen and Sissy Spacek, playing young hedonists on a murder spree.
