Trivia

If the main title music sounds a bit inconsistent with the crime/thriller theme of this film it is because it was recycled from the outdoor drama "Stormy", a 1935 Universal picture which, coincidently, also starred Jean Rogers. See more »

Watch NIGHT KEY
23 March 2017 | by – See all my reviews

I just got through watching NIGHT KEY over the weekend and remembered why Boris Karloff was one of the top actors during Hollywood's Golden Age. Not only could he do horror with one hand tied behind his back just to make it fair to other actors, he could do mainstream and action fare as well. NIGHT KEY can be seen today as an ancestor to all those high-tech epics that we've seen these days. It's time to scope out NIGHT KEY. It is included in a five-movie DVD collection, but worth the trouble. That's all.
