2:00 pm Mysteries of the Unseen World

Take an extraordinary journey into unseen worlds and hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible. The film uses innovative high-speed and time-lapse photography, electron microscopy, and nanotechnology to transport audiences to an enthralling secret world of nature, events, and breathtaking phenomena not visible to the naked eye.

Olivia Fehlberg will introduce this film presented by National Geographic Entertainment and Day’s End Pictures and narrated by Forest Whitaker.
