On Friday evening we all watched Trent's Last Case - the 1952 version, starring Michael Wilding, Margaret Lockwood and Orson Welles. It was fine, though not as good as the original book by EC Bentley, which I read many years ago and was very good (it was, as I remember, written to make fun of detective fiction yet ended up becoming a classic of detective fiction). The film told the story pretty faithfully, I suspect, but just didn't have a lot of life and wit to it.
Interesting to think that Michael Wilding and Margaret Lockwood were big stars at the time but most of their films are little remembered now. Orson Welles has an aura of not having done very much after his big start, but was actually in loads of things. He looks a bit odd in this - I'm not sure if it's because he's between youthful vigour and aged corpulence, or just that he's made up rather oddly for no apparent reason.
Also fascinating to see a young Kenneth Williams in a small part, with an excitable speaking role as an witness at the inquest.
