The character and murderous career of Dr. Martout was based on fact. The real doctor, very much as depicted in the film, was a Dr. Petiot, who was tried and convicted of 26 murders, but suspected of over 100. He was executed by guillotine.
Despite being set in France circa 1942, all of Anna Gaylor's costumes and hair styles are strictly 1957.
