Most of Marlene Dietrich’s best, most glamorous and most outrageous movies are not included in tonight’s one-evening salute (what, no Scarlet Empress?). But there are some relative rarities here, including such early films as 1936’s Desire (at 8 p.m. ET, pictured) and 1933’s Song of Songs. But of this bunch, the classic arrives late, with the 2 a.m. ET showing of Dietrich’s late-career triumph, 1957’s Witness for the Prosecution.
