They ARE being shown on TCM. I've seen them listed many times. I suggest you subscribe to TCM's monthly "Now Playing" magazine. It's Great!. Don't worry, you'll find what you're looking for....ALL of it! And More! Meanwhile, try a couple of wonderful Karloff's on Wednesday night, the 19th; "The Body Snatcher" with Boris and Bela and Henry Daniel and "Bedlam", from 12:30 AM till 3:30 AM (Pacific)...actually that's very early on Thursday, the 20th.
I saw a Mr. Moto movie listed in "Now Playing" a year or two ago (He made at least six) and missed it. As a kid I LOVED them. He was the king of ju jitsu before "martial arts" were ever heard of. Any chance it'll/they'll be back? (a "rider" question....who was the first Director hited for Ross Hunter's "Airport"? He had delays on the start because of bad weather in Mineapolis, became ill and died and was replaced by George Seaton.
