"Private Worlds" is a very good film, so when I call it 'soapy psychiatry' it's not really an insult...more an idea what to expect when you watch. It is set at a psychiatric hospital AND there are a lot of soap opera-like elements to the story. And, it's also very well worth seeing.
The story begins with Dr. MacGregor (Joel McCrea) interviewing to be the new administrator at the sanitarium in which he's worked. However, he's passed over for an outsider, Dr. Monet (Charles Boyer)....a man who appears much more old fashioned in his notions about psychiatry. As for Dr. Everest (Claudette Colbert), while she isn't thrilled at the rather sexist notions by Dr. Monet (who believes women do not make good psychiatrists), she is willing to reserve judgment and work with him.
An odd thing happens that I did not expect. Dr. Monet's vicious sister (who would today most likely be diagnosed with a Borderline Personality) begins flirting with Dr. MacGregor and does much to harm his marriage. It ultimately results in his wife nearly dying...and forces Dr. Monet to face up to how evil and manipulative his sister is. What's next? See the film.
While the film is not without problems, overall it's very well acted and presents a compassionate form of mental health treatment...a bit ahead of its time. Occasionally, it seems a bit unrealistic (such as how easily Dr. Everest is able to 'cure' patients with just a few words) and the casting of Helen Vison as Charles Boyer's sister is just dumb, as she has no French accent and his is very thick! Still, I could overlook these things and the film is quite good...so much so that I am surprised it's rarely seen on TV and should be.
