I remember watching a pair of low-budget TV movies in the late 70s, both of which gave me the impression the writers got their source materials confused.
"DR. STRANGE" had an English "ancient one", and his arch-enenmy was Morgan Le Fay. Now... this CAN'T be a coincidence... but less than a year earlier, Marv Wolfman & Carmine Infantino's early run of "SPIDER-WOMAN" featured an old English guy who was an ancient magician, and Morgan Le Fay. Sounds like somebody in Hollywood was looking at the wrong comics, doesn't it?
And then there was "MANDRAKE". Just to be "different" (or something), Mandrake wore an open-to-the waist shirt that made him look like he stepped out of a late-70s DISCO... and his sidekick, Lothar, wore a TUXEDO. Gee, it was almost like they'd swapped characters.
But the other thing that confused me was... they briefly touched on Mandrake's origin, which involved a plane crash in the Himalayas, and his being raised by a group of Monks on a secret city hidden high in the mountains. Oh, and he had an amulet and used REAL magic. It seemed to me somebody's borrowed a few elements from DR. STRANGE comics. Or "LOST HORIZON". Or both.
But then, some years later, I read a reprint of Mandrake's origin from sometime in the early 50s (I think). And the one in that movie was EXACTLY what was in the comics! This was akin to my learning, years after-the-fact, that the Lynda Carter WONDER WOMAN origin story was ALMOST IDENTICAL to the one from 1941. When I saw that on TV first-run, I had NO IDEA that TV-movie had been so authentic in some respects.
Growin up, I always figured Mandrake used some form of mass hypnosis. But, HOW the hell did this work? That didn't make sense. It was cool though. Only decades later, did I find out, all the time, Mandrake used REAL supernatural magic... which he manifested in the form of "hypnotism". So he was passing it off as some kind of stage trickery... fooling people so they wouldn't have a clue he was using REAL magic. That's like a double layer of trickery.
Recently I saw 2 other versions of "MANDRAKE" on Youtube. The first was a 12-chapter movie serial from the late 30s. The same actor who played him also played THE GREEN HORNET and THE SPIDER, but while he was GREAT in both of those, he looked all wrong as Mandrake. Apart from NOT being thin as a rail, he was clean-shaven. Also, his sidekick was called "Luh-THAR" (emphasis on the 2nd syllable). How could they get THAT wrong? And, Mandrake's girlfriend was some generic blonde... NOT Princess Narda. Oh yeah... and Mandrake in the serial NEVER once used hypnotism. WTF!?
Then I saw the UNSOLD TV pilot from the 1954. WHOA!!! This one got all the right details RIGHT. It's a damn shame it didn't go to series. Woody Strode played Lothar, Lisa Howard was Princess Narda.
I can believe King Features doesn't care about their properties. I remember the Sci Fi Channel "FLASH GORDON" series. What a wrong-headed abortion that was!
