Yes! I had forgotten about the scene you mention! (We do need to compile all of these "Chan sightings"!) It is interesting, as you note, that that picture was released by 20th Century-Fox with their obvious connection to Charlie Chan. Also, it was very soon that the Fox Chan films would be released and promoted for television showings.
I would also like to thank Russell for sharing his "find"!
Dear Steve: "Leverage" is on TNT airing on Sunday nights at 9:00pm. episodes are repeated and may be available On Demand. The murder mystery format is not a regular feature. The program follows a kind of combination Sting-Misson Impossible format.
It would be fun to start a "Chan Sighting List" on this website. There are so many cameos from Chan and Moto. [Mr. Moto appears in a Looney Tunes cartoon with Porky Pig.]
Thank you Russell for the information. I'll try and check out the series on TNT.
