The Treasure of Lost Canyon (1952)

Synopsis
Gentlemanly William Powell is cast spectacularly but effectively against type in Treasure of the Lost Canyon. Powell plays Doc Brown, a somewhat seedy frontier sawbones who takes orphaned David (Tommy Ivo) under his wing. Doc knows that David is being victimized financially by crooked-attorney Lucius (Henry Hull), but he's in no position to do much about it. He'd also like to return to his prosperous practice in San Francisco, but again he's powerless to do so. Things take a surprising turn when David and the Doc go on a search for a chest full of treasure that the boy had discovered earlier in the proceedings, but had tossed into a treacherous waterfall. Alternately spine-chilling and hilarious, Treasure of the Lost Canyon was by far the most uncharacteristic William Powell vehicle since The Senator was Indiscreet (1947). ~ Hal Erickson, All Movie Guide
