"The Key" starts off promisingly with atmospheric photography as British troops track down a Sein Fein leader. Apparently Warner Bros thought this wasn't enough, so halfway through the film a love triangle is introduced between William Powell, Edna Best and Colin Clive. All it succeeds in doing is derailing the film into very familiar territory. Seeing Colin Clive making dead bodies with a gun rather than bringing them back to life in a lab sparks some interest but other than that he spends his time looking glum (did he ever smile?). William Powell begins the film with an accent and a "right-ho, pip, pip" clipped speech that vanishes by the third reel and he and Edna Best (in her first U.S. film) have absolutely no chemistry. Director Curtiz does well until the highpoint of the love story where he pulls the camera out the window into the fog and goes into a flashback that looks like it belongs on a 1890 stage. Add to this a criminally underused Donald Crisp and a hokey ending and you have one missed opportunity.
