Today and tonight, TCM is devoting its schedule to Marilyn Monroe. This makes room for plenty of her classics, including 1956’s Bus Stop at 6 p.m. ET and 1953’s Niagara at 10 p.m. ET. But the real treat, leading off prime time, is 1955’s The Seven Year Itch, co-starring Tom Ewell. He plays a Fifties-era Madison Avenue advertising genius – a prototype for Don Draper of Mad Men, only frumpier – and she plays an apartment neighbor upon whom he projects his romantic fantasies, especially while his wife is away. This is the movie where Monroe stands atop that subway grate in that billowing white dress – but it’s also the movie where Ewell, imagining a private visit with Monroe, envisions them as sophisticates, drinking champagne in evening clothes as he dazzles her by playing Rachmaninoff on the piano.
