With plenty of wit and plenty of entertainment, "Another Thin Man" is a worthy entry in the enjoyable Thin Man series. Although much of it relies on the now-standard formula, the characters never seem to lose their charm, and the writing is still resourceful. The pairing of William Powell and Myrna Loy alone would make any movie worth watching, but there is plenty more here as well.
The story combines the usual oddball assortment of characters with an interesting mystery, plus some new developments in the private lives of Nick and Nora. Their need to look after their new baby even as they get more and more involved in the mystery creates some good moments. The mystery itself is pretty good, with twists and plenty of action. The supporting cast is solid, and a couple of them get some good moments of their own.
This feature has just a slightly different feel to it, at least in comparison with the first in the series, in that it seems to have a little less humor and a little more serious action. But it has more than enough of both to make for an enjoyable movie.
