Garrett J. Kleven is the creator of Hollow Moon, an ambitious science-fiction screenplay set 66 million years in the past. The story reimagines Mars, Earth, and the Moon through an interplanetary war that destroys civilizations and alters the future of the solar system.

Through a narrative of hollow moon-vessels, plasma warfare, bio-engineered creatures, floating Reptilian palaces, and genetic transformation, Kleven explores survival at its most extreme. Hollow Moon asks what a civilization might sacrifice to escape extinction, and whether humanity’s beginning could be connected to a history buried long before recorded time.
