As our Internet connection at work blocks the site featuring the trailer - presumably YouTube - I will take a look at home this evening. This is a treat that I look forward to seeing!
Thank you. I was able to access it at home. Very nice! Even more interesting! I thought that this could be the solution to the mystery of the Charlie Chan still from Cuba that I came across a year or so ago, but no. That is still unexplained. It looks to be a later production with another actor as Chan. Still, this is a very nice find!
