This was rather a stodgy series, illumined by the obviously barbed comments between the great detective and his Number One Son, who usually puts his foot into it.
Barry Chan appears in 25 of the stories: Nos. 4 to 13, 15 to 17, 20, 22, 24 to 33.
Episodes 1 to 5 were made in USA, the remaining episodes were filmed in England. Some limited location shooting was done in other European countries in which stories were set: France: Story 6 (Paris) and 12, Brussels: 16, 20 and 22, Amsterdam: 19, Rome: 27, 35 and 37,Venice: 33 and 34.
Best episode: #33 Man with 100 Faces. Alan Wheatley claimed this was one of his favourite roles.
Dud episode: #2 Secret of the Sea- though nearly all the American-made stories are poor. Best moments are Charlie Chan's wise sayings. Here's one from story #7 -
"Fading flower no longer attracts bee."
