Can you tell me the Chalie Chan film in which this scene occurred: one of Charlie's colleagues meets up with an old friend and they begin to chat about old friends and relatives. There are a string of lines in which each one breaks in and finishes the other's sentences, semingly mindreading each other as to whom he was talking about and going from there to fill in a few words, back and forth. Hillarious. I'd like to find and rent it.

Warren,
There are at least two that I can remember that involve Chan's chauffeur, Birmingham Brown (Mataan Moreland):

The Shanghai Cobra

Docks of New Orleans

This is presuming that my memory is still functioning!

Virginia

Yet another one is THE SCARLET CLUE (takes place in a radio station)

Both SCARLET CLUE and SHANGHAI COBRA are on vhs/dvd as part of the Turner chanology collection. You can probably get them through netflix.
