This animated, wide-screen, stereoscopic feature film melds Arthurian legend with STAR WARS technology. The story involves a young robot-enslaved human hero who retrieves a magic sword to help free the other humans in a huge underground world. Ascending to the surface, the hero meets a
piratical captain of a spaceship, and the two battle the forces of evil with the help of robots and otherworldy critters. A few mild curse words give this children's film its PG rating.
