Agree 100%. I can't imagine why anyone would consider
Brief Encounter (1945) a noir. It's a very good classic romantic drama starring the great Celia Johnson, and Trevor Howard. I liked it more than you did. Sometimes I think that people tend to consider any '40s B&W film to be a
noir..
Do you recall Celia Johnson in 1969's
The Prime of Miss Jean Brodie? She won the BAFTA award for that role as the headmistress, and she was superb. IMO "Jean Brodie" was a wonderful film. Really put Maggie Smith on the international map.
