Charlie Chan movies are an acquired taste. I'm assuming that you have that taste or you wouldn't be looking at this review of the video.
I hadn't seen this movie in over 30 years, and I was curious to see if my obsession with Charlie Chan had survived. I must report that I'm still hooked.
Why? The plot is extremely compact, complex, and well developed. Even knowing who did what to whom, I was fascinated to see the story unfold.
I expected to be bothered by the treatment of Charlie as a Chinese American, but that was handled with reasonable aplomb. Charlie is obviously the smartest guy in the room, and everyone figures that out pretty quickly. Once they know him, they all love Charlie. There's one scene early on where Charlie is patronized by a new acquaintance, but he handles it all with grace. The rest of the time, Charlie receives the kind of treatment that a detective king might command. Warner Oland graciously takes it all as his due.
Those who love Keye Luke who played Lee Chan in the series will be pleased to see that he has a good sized role in Charlie Chan in Paris.
Those who love Apache dancing will enjoy that scene.
What really shocked me was how poorly the film represented Paris. Aside from some French names and a pair of Apache dancers, no one in the film seems to be French. The effort is most amateurish except for an interesting trip through the Paris sewers which is rigged with an unexpected gag.
