Steve, loved that excerpt from the novel about the trade winds, cocoa palms turning their heads, and John Quincy kissing Carlota Egan, etc...Very nice!
Ref the above link. It appears, for a moment in time, the trademark "Charlie Chan" was free (or dead Jul-Sep 2013) with a notice of abandonment filed 15 July 2013! But alas they were renewing it and finalized 22 Oct 13 :(.
Thanks for explaining the issues. I thought that someone in years past had posted on Kurt's Chan Message Board something about copyright issues regarding the lost films, and that ownership might be in dispute if one of these films were now found, but I don't remember the details. I suppose we will find out about all of the legal angles if we are ever fortunate enough to find a lost Chan film.
