Just saw this today for the first time, courtesy of Kino Lorber's brand-new 2K master on Blu-Ray. Not quite what I expected-- LOTS of fun!
Apparently, like a number of much-later films involving classic characters (Conan, The Shadow, The Saint), someone in Hollywood decided to tack on an "origin" story that was never in the books. IN this case, they have Fu begin as a humanitarian before his family is killed by army crossfire. At that point, he becomes a diabolical serial killer bent on revenge "to the 3rd generation". (Imagine if Michael Myers had a brain-- and tended to never shut up, explaining his plans at length, like a Bond villain!)
The image on the new Blu-Ray, while still damaged in spots, is mostly pretty sharp & stunning. Apparently, the film has NEVER looked this good in my lifetime. I wish someone had put in more effort with the sound, which is wildly inconsistent. The 2nd half of the story seems more like a filmed stage play than a movie, but a LOT more fun to watch than, say, the 1931 "DRACULA".
One long sequence takes place at an old mansion perched on top of a very dangerous-looking cliff, while the climax is entirely in a pair of rooms in Fu's hideout in Limehouse. At one moment, Fu points out the similarity to a classic "melodrama", which only emphasizes the sheer ridiculousness of the cat-and-mouse game situation. But I had a big smile on my face the whole time, so, I guess, no real complaints!
It cracked me up to see 2 "Batman" actors in this-- "Alfred" from 1943 and "Gordon" from 1966. Made me think the '66 TV show could have really used an Asian super-villain in its roster!
I've noticed of late that quite a few early Paramount films are only available in TERRIBLE prints, which has led me to believe the studio really doesn't give a damn about their oldies. I've recently seen 4 "Philo Vance" films that were made by Paramount, and all of them were in dreadful shape. As 3 of those I rate as extremely-good early talkie murder mysteries, I find myself wishing someone like Kino Lorber would make the effort to restore THOSE films as well. Silents and early sound films are their own special kind of art form, and I find one really can't appreciate them to their fullest unless you're watching a REALLY CLEAN print. This one isn't perfect, but I suppose for now, it'll do!
