Wednesdays and Fridays this month, TCM is working its way through “50 Years of Hitchcock” – and I’ve seen most of them, and recorded the rest, because I’ve never seen them in order like this. What a treat. What a showcase, Tonight, the tribute continues, with 1943’s Shadow of a Doubt at 8 p.m. ET, 1944’s Lifeboat (10 p.m. ET), 1945’s Spellbound (midnight ET), 1946’s Notorious (2:15 a.m. ET), and 1948’s The Paradine Case (4:15 a.m. ET). Watch, in particular, for the Salvador Dali dream sequences in Notorious, and, of course, for Alfred Hitchcock’s playful cameo appearances in each and every film. How, for example, does he show up in Lifeboat, which is set entirely upon a cramped lifeboat adrift at sea? See the accompanying picture.
