On the Roku Channel I’ve been watching Leslie Howard’s son Ronald as Sherlock Holmes, in the 1950’s TV series. The shows are good fun, and being in the public domain they’re widely available.
The old Alfred Hitchcock Presents series is also on the Roku Channel. Ronald Howard appears in an adaptation of Ambrose Bierce’s 1890 short story, “An Occurrence at Owl Creek Bridge”.
Howard as a Southern plantation owner was a clever bit of casting, considering that his father was Ashley Wilkes in Gone With the Wind. I can’t embed the Hitchcock episode, but this link will take you there.
