M.M. you are probably right...karate chops a plenty (you don't see those too much any more :). I believe that was what they'd planned when Lucy Lu was considering a Chan movie as his granddaughter, around 2006.
In my humble opinion, it will take someone like Guy Ritchie (of the recent Sherlock Holmes films) to produce a true Charlie Chan film. You got any pull? :wink:
Sorry, no pull here. But once public domain kicks in, if any enterprising independent filmmaker with a gift for gab can convince somebody to bankroll their own film version of the character, they’ll be in the clear to do so.
