Dr. M schlägt zu (1972)

A mad scientist is attempting to get the plans for a death ray from a nearby research facility.

Es geschah am hellichten Tag (1958)

Having doubts about the guilt of the obvious suspect in the murder of an eight year old girl, a police detective decides to investigate the case on his own.

Toned-down adaptation of a much darker Friedrich Dürrenmatt story is well-made with a competent cast (Gert Fröbe is very convincing as the disturbed child murderer), but the happy ending is obviously forced on to please a larger audience.

The Brain (1962)

A millionaire businessman's brain is kept alive after a fatal accident, and communicates clues to a doctor on the trail of the killer.

Above-average sci-fi drama with a good cast and some excellent cinematography; the plot is silly, of course, but is treated more like a crime mystery.

Halliwell (no star): "Twisty remake of Donovan's Brain, not too badly done."

Maltin***: "Good remake of DONOVAN'S BRAIN..."
