Just finished watching MR. WONG, DETECTIVE on VEOH. It was made by Monogram Pictures, so I assume the movie is in the public domain, and therefore, legally postable. Bad detective, eh?"

It's a good series. All available via Oldies.com (Alpha video) for circa $5 apiece. A total of 6 fllms -- 5 with Karloff, and the last with Keye Luke as a younger Mr. Wong.
One of the interesting things about the Wong scripts is that almost all of them were reused for Chan films with Roland Winter (same screenwriter).
Enjoy
