Indeed. I think I read somewhere that the Scarlet Pimpernel was Howard’s favorite role and movie, not the one he’s most famous for, i.e., “Gone With The Wind”-Lesley Wilkes. In fact, I think he actively disliked GWTW and his character in it.
It’s understandable since his character is more stronger and heroic in the 1934 film.
His son played Sherlock Holmes in a British series at the U.S. from the 50's.
