You might want to avoid reading the plot description of "Disturbed" here on IMDb, as the sole one available rather bluntly gives away the essential plot twist of the film's final five minutes. Admittedly this denouement isn't particularly hard to predict, but still
it kind of spoils the fun factor.
"Disturbed" is an overlooked but vivid and entertaining enough psycho- thriller feature from the early 90's. The plot and setting are overly familiar, but the film nevertheless manages to keep you glued to the screen for an hour and a half. This is mostly thanks to a handful of truly atmospheric sequences and the more than adequate acting performances from the ensemble cast. "Disturbed" stars B-movie favorite Malcolm McDowell in his accustomed role of dangerous doctor, but he receives excellent support from multiple recognizable faces in the roles of his mental patients. There's Geoffrey Lewis ("The Devil's Rejects", "The Lawnmower Man"), Irwin Keyes ("House of 1.000 Corpses", "Chained Heat"), Clint Howard ("EvilSpeak", "Ticks"), Emerson Bixby ("Deep End") and even that creepy little guy who played all the Oompa-Loompas in Tim Burton's "Charlie and the Chocolate Factory". The film is already worth checking out if only to see all these names star as loonies! McDowell is the widely respected Dr. Derrick Russell, brilliant psychiatrist and owner of an eminent mental clinic. He also has the bad habit, however, of occasionally sneaking into the rooms of his female patients to drug and rape them. When he tries to rape the newly arrived patient Sandy Ramirez, she accidentally dies from an allergic reaction to the drugs. With the help of another patient, Dr. Russell develops an evil plan, but then the next morning the body appears to be vanished. Strange things begin to occur after that, and Dr. Russell is wondering if he isn't degenerating into a state of madness himself. "Disturbed" is a derivative and predictable thriller, but it's fairly uplifted thanks to McDowell's presence and thanks to the imaginative cinematography. The relatively unknown director Charles Winkler (son of producer Irwin Winkler) makes the asylum extra sinister and its inhabitants extra morbid through grim camera angles and eerie sounds of laughter, creaking doors, etc
