Friday nights are good times to nestle into the couch and watch a good movie on TV – and August is the month when TCM devotes every day, as well as every night, to a single star or filmmaker, presenting a 24-hour marathon of related movies. This year, the celebration begins with Jane Fonda, and the party’s already begun (it started at 6 a.m. ET) with 1960’s Tall Story, the actress’ first movie, in which she played a cheerleader opposite star college basketball star Anthony Perkins. Other movies on the schedule today trace her very quick development: 1962’s Walk on the Wild Side (9:45 a.m. ET) gives her a role that morphs from sweet innocent to hardened prostitute; 1979’s The China Syndrome (5:45 p.m. ET) gives her a great role in a great movie, playing a fluff TV reporter determined to report on meatier stories, and stumbling into a nuclear power plant contamination story in an intense drama (Jack Lemmon is fabulous) that exploded in theaters just as Three Mile Island almost exploded in real life. And later tonight, there’s the giddy cowboy comedy Cat Ballou (9:15 p.m. ET), as well as Fonda’s first personal Oscar-winner, Klute (12:15 a.m. ET, pictured), in which she plays a high-priced prostitute who may be the key to murders investigated by Donald Sutherland. He’s the one named Klute by the way. She’s Bree.
