A little more than ten years ago, I read the novel "Charlie Chan Carries On" when I was also watching various Charlie Chan movies and reviewing them here on IMDb. Because it's been so long since then, all I really remember from the book was that Chan didn't appear in it until it was in the middle of it. So while watching this movie version (the second, after the previous filmed version which was the first time Warner Oland played the role. That version is lost), I didn't remember the characters that were now depicted from that novel. Anyway, this was another enjoyable film in the series with Sidney Toler doing fine in the role of the famous detective. Ditto Victor Sen Yung as his son Jimmy who's always in over his head but also always well meaning. So that's a recommendation for Charlie Chan's Murder Cruise.
