Here's a random thought. Tonight for the first time ever, I got to see Charlie Chan's Secret. I picked this movie because before the changeover, the old Charliechan.net gave this movie one of the very rare five panama hats. My only regret was that I did not write all of these ratings down before the website underwent it's overhaul yesterday, as it's no longer listed.
I can clearly see why this movie deserved such a rating. Holy crow was that one good! I have seen quite a few of these movies, and now with this box set, I will see all the Oland Chans that are known to exist. This is a great opportunity for me.
I'll chime in more later with stuff about the other movies. The only other one I saw was Black Camel and I quite liked it.
