 Columbia s first 3-D production (released originally in Sepiatone) and also the first 3-D feature from a major studio---"Bwana Devil" was an indie production distributed by United Artists---has a story featuring gangster Steve Rawley (Edmond O Brien) who, while in jail on a robbery charge, undergoes an experimental brain operation designed to eradicate his criminal tendencies. He loses his memory and is kidnapped by his old cronies who want to get their hands on the hidden loot for which he has been serving time. He eventually, through a series of wild dreams, recovers his memory before the climax in an eerily-lit amusement park, highlighted by a wild chase on and over a roller coaster.
