So far as I know offhand Fox produced only two stereoscopic films in the classic era: Inferno is a personal favorite, an under-rated film noir along the lines of Bad Day At Black Rock, which it resembles, and directed by the under-rated Roy Ward Baker who would later helm the remarkable A Night to Remember.. Baker works the landscape to get the most out of 3-D. The stereoscope cinematography in Death Valley by Lucien Ballard is worth seeing. Gorilla At Large has been released flat on DVD. It's a well-produced B movie and a hoot for audiences, but the stereoscopic photography achieves perfection and surpasses many A-budget 3-D films. For sheer camerawork these are two of the best 3-D films, and they are beautifully preserved.
