EXPERIMENT PERILOUS is another film noir of the 1940s about a family who seem to be tinged with madness. The setting is a house full of hidden secrets, where a doctor (the solid George Brent) arrives after being drawn into the story by meeting a woman on a train who ends up dead soon after. This film mainly gets by thanks to a strong and ethereal performance from Hedy Lamarr as a rather unsettling kind of femme fatale character; there's little in the way of plot but the whole thing is laced with atmosphere and subtle meaning. It's very well shot, too.
