I trust that you are enjoying the Chans that have been released thus far by Fox. It has been a long wait, but, we will soon have all available Charlie Chan films available on commercial DVD with the release of Volume Five in September.
As for "The Closer," as I am not familiar with that series, I do find it interesting that the person you mention uses the "Thank you so much" made famous by Charlie Chan. That, alone may entice me to watch an episode...
