I’ve been watching selections of film noir as recommended by the wikipedia page on such things. First up was Blast Of Silence (1961) which had a kind of ameteurish feel to it but liked it. And it’s also notable that about half of the story is told by a narrator in 2nd person.
The second film was The Manchurian Candidate (1962) which was based on a book—aren’t all the best films adapted from books? Frank Sinatra, and evil Angela Lansbury, a killer plot and some really clever scenes (see below) – what’s not to like?
