The "Return of Charlie Chan" could have made it as a great mystery TV series during the 1970s.

Producer Jack Laird has a fine list of writing credits related to the mystery genres, i.e. Night Gallery, Kojak, and Switch. Gene R. Kearney also has a great list of writing and directing credits. Director Daryl Duke was a native of Vancouver, where the film was shot. His credits included: Night Gallery, Circle of Fear, and The Thorn Birds. This film really could have worked as a weekly TV series. All the elements were there. Too bad it wasn't a go.
