Just watched this, the first of the Monogram Charlie Chan movies after Fox dropped the Honolulu detective two years before, on DVD. It has Chan as a government agent in Washington, D.C., investigating a murder of a scientist who's invented a weapon used to stop some enemy spy missions. I'll stop there and just say that at just a little over an hour, there isn't too much in the way of excitement especially since nearly the entire thing seems to take place on a mansion but there are some good atmospheric shots and a few good suspenseful moments and also some amusing comic relief courtesy of no. 3 son Jimmy (Benson Fong), no. 2 daughter Iris (Marianne Quon), and, in his first appearance, chauffeur Birmingham Brown (Mantan Moreland, who isn't as outrageous as his later appearances in the series). So in summary, Charlie Chan in the Secret Service is a pretty entertaining first entry for the series at its new studio. P.S. In once again identifying someone from my favorite movie, It's a Wonderful Life, Sarah Edwards-who was Mary's mother in that Frank Capra classic-plays Mrs. Hargue, a housekeeper here.
