The premise of Dangerous Partners was very intriguing: survivors of a plane crash find a dying man carrying four separate wills naming him the beneficiary. However, after the first five minutes, that premise transitions into something else. If you're looking for a disaster flick, this isn't it. It's more of a cat-and-mouse, Nazi-conspiracy mystery where you don't know which characters you can trust.
Edmund Gwenn, in the only role I've seen him in where he has brown hair, plays the dying man in the first five minutes. He doesn't die, and instead, he and the two leads, James Craig and Signe Hasso, are in a race to track down the wills and claim the money. James tries to impersonate Teddy so he can get rich instead, but there are double-crossings, political subterfuge, and tons of confusion. And while James thinks Signe is falling in love with him, perhaps she's only pretending so she can get half (or more) of the inheritance money. The biggest question of all, however, is why the normally jolly Edmund Gwenn would take on the role of the villain. He's a very convincing bad guy! He's cold and callus, ordering henchmen to beat up women and pulling guns on innocents. All in all, this wasn't my favorite movie, and it's not one I'd really recommend if you have a free afternoon; but if you're anxious to see it, it won't hurt you.
