Born To Kill (1947) - absolutely classic top-notch noir and there’s not the slightest doubt that this is noir. Strange, overheated and disturbing.
Nocturne (1946) - great hardboiled crime thriller starring George Raft, perhaps not absolutely noir if you’re a purist but an excellent movie.
Johnny Angel (1945) - George Raft again in a terrific very noirish crime thriller.
Wide Boy (1952) - a fine British noir with a splendid performance from the very underrated Sydney Tafler.
Assassin for Hire (1951) - another excellent British entry and another extremely good performance Sydney Tafler.
And while it’s a very large stretch to call it film noir Corridor of Mirrors (1948) is an unusual and exceptionally interesting British gothic melodrama with a slight noir flavour to it.
