The fact that Doctor X was shot in color was pretty rare in 1932 with most of the studios existing from day to day during the Depression. Very few had money to splurge on something like this. Knowing that I'm surprised Warner Brothers didn't bother to use it on one of their Busby Berkeley spectaculars.
There have been a string of mutilation killings in New York, really horrible stuff and forensics has determined the weapon used was a special kind of surgical scalpel only in use at a particular scientific institute. The one headed by Doctor Xavier the Doctor X of the movie title.
Atwill's got some pull with the cops because they allow him 48 hours to find who the killer is and save his institute some scandalous press. The press is in the form of Lee Tracy a determined reporter who sneaks into the institute looking for the inside scoop. He meets up with Fay Wray who is Atwill's daughter, but even she doesn't deter him from his mission.
Horror stories were not the Warner Brothers specialty and when you consider what was coming out of Universal at the time, Dracula, Frankenstein, and The Mummy, Doctor X looks pretty second rate besides them. No monsters in this film except the truly monstrous human being who is doing all the homicides.
Warner Brothers seven years later did The Return Of Doctor X which has absolutely nothing to do with this film and provided Humphrey Bogart with one of the worst roles in his career. Next to that one, Doctor X is like Citizen Kane.
