Thursday nights in May, on TCM this month, belong to Marlene Dietrich, and tonight’s lineup, ending the month, has some late-career must-see films. In prime time, there are two classics. At 8 p.m. ET, it’s the restored and expanded version of Orson Welles’ 1958 film A Touch of Evil (pictured), with that masterful opening shot. And at 10 p.m. ET, it’s 1957’s Witness for the Prosecution, with Dietrich’s masterful climactic scene. Watch them both.
