Long before it became de rigueur for animated features, this sci-fi fantasy was the first one to be made and released in 3-D. In the year 2985, in the depths of Mine-World, humans are enslaved by despot Zygon—but hope arrives in the form of a mythical sword that can be wielded by nascent hero Orin. Exciting battle sequences, colorful characters, and painstaking animation all pop in the format.
