RIFFRAFF. RKO Radio Pictures, 1947. Pat O’Brien (PI Dan Hammer), Walter Slezak, Anne Jeffreys, Percy Kilbride, Jerome Cowan. Director: Ted Tetzlaff.

   It’s a question that needs investigating, but while I recognize the truth of that statement, I haven’t yet done so. Here it is, though: Who came first Dan Hammer, or Mike Hammer? Both made their first appearance in 1947, and that’s as far as I personally have gotten. What is not up for doubt is the obvious followup question: Which of the two made the bigger impact on American pop culture history?

   While there are quite a few good things to be said about Dan Hammer, and Riffraff, his only appearance in motion picture form, he’s remembered by almost nobody. Almost all of Riffraff takes place in Panama, where Dan Hammer, as played ever so suavely by movie actor Pat O’Brien, is the to-go-to man about town. He knows the people to see, the ropes to pull, and every so often, it is said that folks in need of help actually pay him for the tips he gives them.

   He may have hit the jackpot this time around, one that may be worth several thousand dollars to him – if only he can find the map to several Peruvian oil wells potentially worth many times that amount. With both Jerome Cowan and Walter Slezak in the picture (pun intended), the competition is fierce. And of course there’s a girl involved. Just whose side is she on?

   Unfortunately, the dialogue, acting and the photography are all individually and collectively better than the plot which is as barebones as that previous paragraph would suggest. In quite unusual fashion, the opening scenes go on for six or seven minutes with no dialogue, an interesting approach in starting a B-movie mystery back in 1947. It is as if those in charge in production were striving for more, and in fact I think they were almost but not quite successful in doing so.

   Unfortunately (for the second time), the romance between Pat O’Brien (48 at the time) and Anne Jeffreys (half his age at 24) falls totally flat, or so it seemed to me. No sparks. He’s middle-aged, a bit paunchy with a receding hairline, and she’s young, blonde and vivacious. Of course she’s leaving Jerome Cowan for him, so maybe there’s a message somewhere there.

   But do watch this movie if you get the chance, especially if you’re a fan of minor league PI’s located in out-of-the-way places. And any movie with Percy Kilbride in it is always worth watching, no matter what kind of old movie you’re a fan of.
