I am very struck by the fact that a great many of the movies mentioned are modern, by which I mean movies which have been mostly made in the last twenty or so years.
In fact, I suspect that some of the older classics are completely unknown to many who have posted here, and so do not feature.
A few others to ponder, from a variety of eras>
"The Wizard of Oz" - a stupefyingly example of brilliant movie making, and an object lesson in how to meticulously adapt an adored classic ('The Hobbit', please take note).
Two (black, polished, dark) comedies from the British Ealing stable which date from the post war period:
"Arsenic And Old Lace", and (my personal favourite, this) "Kind Hearts And Coronets".
An elegant, tense and beautifully made homage to film noir style movies (and another meticulous adaptation): "LA Confidential".
