Song of the Thin Man has a lot of strong sequences and the many screenwriters sting them together well enough, but can’t figure out a pay-off. Some of the problem seems to be the brevity–while director Buzzell does an adequate job and Charles Rosher’s cinematography is good, none of the scenes end up having much weight.
The film does give William Powell and Myrna Loy more to do in regards to their parenting–with Dean Stockwell as their son–they have less to do as far as investigating. Song runs less than ninety minutes and even another ten of a good mystery would help immensely. All of those really good sequences are either comedic parenting ones or a single “race the clock” one. Loy excels in the latter.
There are just too many suspects and not enough time spent on them. The script sets up the suspects in the first few scenes and it plays efficiently enough, but then keeps everyone too suspicious to be sympathetic. The script works against itself and Buzzell isn’t at all the director to bring it together.
Of the supporting cast members, Keenan Wynn and Jayne Meadows have the most to do and are the best. Wynn is Powell and Loy’s guide through the nightlife, with the script cutting a lot of corners as to how that tour progresses. It’s either lazy writing or lazy producing. Either way, it hurts the film.
But Song is still entertaining, it just easily could’ve been better.
