Directed by documentary filmmaker Howard Hall, "Under the Sea 3D (IMAX)" is the third film in a loose trilogy of undersea documentary. The first and second documentaries, respectively, "Deep Sea 3D" and "Into the Deep 3D" used 3D and the 70-foot tall IMAX screen to full effect, taking moviegoers safely under the water to explore the diverse wonders of undersea life and underwater terrain. With Jim Carrey providing voiceover narration, "Under the Sea 3D (IMAX)" takes viewers to exotic locations, including Southern Australia, the Great Barrier Reef, Papua New Guinea, and Indonesia as part of an exploration off the so-called Coral Triangle.
