Giving strength to the phase “they’re not making them like that any more” is the classic series of film noir take-offs the Thin Man movies, starring William Powell and Myrna Loy.
The first movie, The Thin Man (1934), was based on a novel by one of the godfathers of noir, Dashiell Hammett, who also worked on the screenplays for the first two movies. However the chemistry of Powell and Loy make the movie of The Thin Man a good deal more fun than the book: classy, witty and all-around a good time.
The movie was such a success it was followed in 1936 by Another Thin Man, and eventually a total of six Thin Man movies were made, ending with the 1947 Song of the Thin Man. To my mind, the three 30s movies are the best, with the feel of the movies changing slightly in the later movies.
