Charlie Chan History
Kamiyama Sojin, Charlie Chan in The Chinese Parrot, was born in Sendal, Japan, on January 30, 1884.
This picture of Sojin is from www.geocities.com/lesingebleucafe/Movies/2003/Paris.html.
It mentions that the first three Chan movies were silents, The House Without a Key, The Chinese Parrot and Behind That Curtain.
I don't know if Behind That Curtain started out as a silent but I do have a copy of it as a talkie. It's technically a Chan movie since Earl Derr Biggers' character does appear briefly but it was made over as a vehicle for Warner Baxter!
