When an old movie isn’t available on YouTube, Archive.org is worth checking. Night Must Fall is a well-regarded 1937 film that was adapted from a stage play, making it chatty and slow by today’s standards. Rosalind Russell is excellent as a very attractive old maid, to use an outdated expression.
The poster frame for the video has the name Douglas Shearer, brother of actress Norma Shearer. She was the wife of MGM studio executive Irving Thalberg, who had died suddenly the year before Night Must Fall. I used to assume that Douglas had a title at MGM thanks to his sister, and he never did any real work. How wrong I was. I’ll say more about him later.
