Grand Hotel (Edmund Goulding, 1932), 7pm, BBC Four
“I want to be alone!” Greta Garbo is at her most diva-ish in this 1932 Oscar winner, a seductive pre-Code melodrama set exclusively in an opulent Berlin hotel. She is a depressed ballerina given a new lease of life after falling for John Barrymore’s Baron Felix von Geigern. Sadly, he has plans to steal her jewels to pay off his debts – but he’s also in love with her so it’s not a simple proposition. Lionel Barrymore’s terminally ill bookkeeper, a young Joan Crawford as a flirtatious stenographer, and Wallace Beery’s bumptious factory owner are other guests adding to the social whirl.
