Welcome. I am very pleased tha you haver enjoyed our humble endevor thus far, and, I hope that your visits will continue to be enjoyable.
As of this time, the only way that fans of Charlie Chan can obtain copies of all the films from the series proper that exist is to frequent the twilight realm of the "grey market" sellers. Hopefully, this will change over the course of the next year or so, as Fox may continue to release its Charlie Chan holdings. It is fairly substantially rumored that Warner Brothers, who holds the rights to the final 11 films in the Chan series, as well as, amazingly, "The Black Camel," will be putting out their own Charlie Chan DVDs sometime this year. The main hold-up seems to be the dearth of good prints of a number of these movies.
So, the outlook is pretty promising for fans of Charlie Chan with regard to one day having access to all existing Chan series movies on commercially produced, authorized, DVDs.
Re: "Grey Market", yep, that's how I got my copies (14 DVD-R's, basically).
Why it's taken this long for Fox & Turner (MGM/Warner) to start releasing their Chan films is beyond me, as it's definitely an untapped market - I expect that the 15 films released by MGM/Warner/Turner (6 Monograms) and Fox (9, including a subtitled "Eran Trece") in the past 2-3 years have experienced sales through the roof, what with properly restored prints and all.
Now, my copy of "Charlie Chan's Secret" is well above average for a public domain transfer, but how I'd love to see a fully restored print giving deserved justice to all it's subtle visual effects/props.
Again, thanks for the warm welcome & I'll end this post with my all-time favorite Charlie Chan quote:
