During the 1930s and 40s, MGM produced many successful "Thin Man" movies starring William Powell and Myrna Loy. They were wonderful little mystery films with a very strong emphasis on humor and the banter between the two leads. Here, MGM tries to make the formula pay off again, but this time with Robert Montgomery and Rosalind Russell in the leads. In so many ways the film was this old formula all over again, but somehow despite their best efforts the two leads just don't make it work as well as Powell and Loy--partly because the Thin Man films are so good it's hard to match them and partly because the script just isn't as good as the Thin Man scripts--it's just too complex and not all that interesting. Still, considering the Russell and Montgomery still are wonderful actors, the film pays off well enough to recommend it. I especially liked Montgomery's easy-going manner, though unfortunately the usually strong characters Russell plays aren't as evident here and she's rather over-shadowed by Montgomery.
So overall, it's not a bad little film--just don't expect the magic of Nick and Nora Charles.
