Bwana Devil 3D
This novelty feature boasts of being the first full-length film in Natural Vision 3-D. Although adding backsides to usually flat actors and depth to landscapes, the 3-D technique still needs further technical advances.
Without the paper-framed, polaroid glasses Natural Vision looks like a ghosty television picture. While watching 3-D, viewers are constantly forced to refocus their vision as the focus of the film changes, resulting in a tiring eye workout.
The Oboler production is full of tricks devised to show off the process, rather than to tell the screen story effectively. The much-ballyhooed point of a lion seemingly leaping out of the screen into the auditorium comes off very mildly. The single gasper is the throwing of a spear by a native, which has the illusion of coming right into the audience.
