Bionicle: Mask of Light, stylized as BIONICLE: Mask of Light — The Movie, is a 2003 animated science fantasy action film based on the Bionicle toyline by Lego, and particularly serves as a direct adaptation to the latter half of the toyline's 2003 narrative. Set in a universe filled with bio-mechanical beings allied with classical element-themed tribes, the story follows two friends from the fire-based village of Ta-Koro on a quest to find the owner of the Mask of Light, a mystical artifact that can potentially defeat Makuta, an evil entity threatening the island.

Lego is a line of plastic construction toys manufactured by the Lego Group, a privately held company based in Billund, Denmark. Lego consists of variously coloured interlocking plastic bricks made of acrylonitrile butadiene styrene (ABS) that accompany an array of gears, figurines called minifigures, and various other parts. Its pieces can be assembled and connected in many ways to construct objects, including vehicles, buildings, and working robots. Assembled Lego models can be taken apart, and their pieces can be reused to create new constructions.
