I think it should be mentioned that although the actors on the big and little screen, Oland, Toler, Winters Nash and Young, just kidding about that last one, who portrayed Charlie Chan may have done so using a pronounced accent their command of the English language was by no means inferior. They spoke it very well. I don't think it could be accurately described as "broken". With the possible exception of Ross Martin I thought they sounded authentic and tried not to be overbearing. The radio version of Chan was a different story. I ones I've heard were very stereotyped and "unreal sounding'. It is this over-the-top perception of Charlie Chan that many of his critics believe is the norm, while the opposite is true.
