If you are a fan of Jacques Tourneur, "Experiment Perilous" is a must-see. This sinister and beautifully photographed period thriller ranks with Tourneur's supreme masterpieces, "Out of the Past", "Stars in My Crown", "Canyon Passage", "Curse of the Demon", "I Walked with a Zombie", and "Cat People". It is imbued with Tourneur's trademark touch of ambiguity and mystery. One of the reasons "Experiment Perilous" is so underrated is that the story does not flow logically. You have to do a bit of brain work to understand it, but if you are already familiar with Tourneur's cinema, this may come as a revelation. The film has often been compared to Cukor's similar costume thriller "Gaslight" which was also released in 1944 but "Experiment Perilous" is a better and more personal work. The opening chance encounter between Dr. Bailey (George Brent) and Cissie (Olive Blakeney) on the train resembles the mysterious chance meetings of "Cat People" and Tourneur's 1956 film noir "Nightfall". It has been said that the film was set in 1903 as opposed to 1944 because Heddy Lamarr wanted to wear period costumes. Lamarr is undoubtedly beautiful and her scenes with Brent and Lukas are exquisite and sensual.
There is an excellent analysis on the film in Chris Fujiwara's book, JACQUES TOURNEUR: THE CINEMA OF NIGHTFALL (1998).
