We know that good teachers can inspire but so too can bad ones. Greg Passmore's science teacher was a football coach whose inability to teach the subject inspired Passmore to become a filmmaker who could share his passion for science with students. His latest film, "inner Earth" (playing now through November 30 at the San Diego Natural History Museum) takes viewers on a 3-D journey through a still vastly uncharted subterranean world.

Greg Passmore has been living and working in San Diego for 13 years. But he has a 30-year career in technology innovation and creative imaging. Passmore says he was a frustrated artist that was inspired by the scientific visualizations he saw in his work. So he decided he wanted to try his hand at filmmaking. His first effort tapped into his love of sports and explored "The Physics of Surfing."

His love of caving brought him to shoot in a cave with 12 million bats for another educational museum film called "Bats." He enjoys describing how in order to find vampire bats you have to first look for a pool of blood on the floor of a cave.

Caving gets his full attention though in his latest film, "Inner Earth." Passmore shot for 3 years all over the globe in order to take viewers on a journey through a still mostly uncharted subterranean world in 3D.

Passmore also runs PassmoreLab based here in San Diego. The company has about 75 employees in three countries performing software development, 3D conversion, and live action filmmaking. Passmore is also an accomplished photographer with his photography appearing in "Vogue," "Cosmo," "Wired," textbooks, and exhibitions. He has also done work on music videos for bands such as Linkin Park.
