Posted this on the old Mystery Movies page too:
Not may posts here lately but thought this may be of interest. For many years (40+) I have been interested in mystery/detective/thriller series films and have managed to view almost all I have tried to find. However, some have always eluded me, notably some obscurer British films. Much to my surprise however, I have discovered that some of these are now available on YouTube although I have not yet had a chance to view them.
One highly sought after series is three films from the 1930s, the first film appearances of Hercule Poirot and starring Austin Trevor as the detective. I was always told these films were lost. However, I have discovered the third one, Lord Edgeware Dies, is available for viewing...I only glanced at the first couple of minutes but a great copy too although it has an annoying time counter at top.
Another series I have sought is a two film 1952 one with John Bentley as "The Toff", a literary character created by John Creasey. Both are available on YouTube: Salute the Toff and Hammer the Toff, and again in decent copies based on a brief glance.
So at least three blanks on my wish list filled in here when I have a chance to view them! Now, if I could only find One is Guilty in the Inspector Trent Series with Ralph Bellamy and the obscure Philo Vance film Night of Mystery (1937) --I know the latter exists but try and find a copy!
