In movies, there wasn't just blackface. There was yellowface too. The Charlie Chan movies always had the character Charlie Chan performed by a white man.
There various sons and daughters were portrayed by Asian actors. At some point, someone at Monogram Studios decided it was a good idea for Mr. Chan to have a driver called Birmingham Brown.
Before Charlie, we have to talk about Mantan Moreland.
AudioMo is an international participation of folks that want to share what they can do with the audio format. This is a captioned audio for those folks that are deaf, hearing impaired or English is not their native language.
