TCM is saluting Best Supporting Actress winners in tonight’s ongoing “31 Days of Oscar” TV festival – and tonight, it saves the best for, well, very late. At 2:15 a.m. ET, TCM presents Peter Bogdanovich’s 1971 adaptation of Larry McMurtry’s haunting tale of small-town Texas life, starring Timothy Bottoms and Cybill Shepherd. Cloris Leachman, while appearing as a series regular on The Mary Tyler Moore Show as Phyllis, won a Supporting Actress Oscar as Ruth Popper, the coach’s lonely wife, in The Last Picture Show. She was only 45 when she won her Academy Award – but in the movie’s black-and-white starkness, playing a woman beaten down by both circumstances and environment, Leachman portrayed someone who looked much less vibrant.
