William Arntz began his professional career as a research laser physicist, developing wave optics simulators for the high energy lasing systems that became the “Star Wars” strategic defense system. He then left the scientific world and spent 20 years studying with two spiritual teachers. During that time he wrote the system management software product – AutoSys -  and sold the company for millions.

Following his lifelong passion for filmmaking, he used the proceeds from that to produce, direct, and write the film  What the BLEEP Do We Know, incorporating his scientific background, spiritual training, and a desire to make people laugh and think.

With co-filmmakers Betsy Chasse and Mark Vicente, William wrote the companion book and created  What the BLEEP: Down the Rabbit Hole to satisfy the public's request for more BLEEP content.

William then moved on to another film which develops some principles from BLEEP in a sociological, urban setting. The film  Ghetto Physics addresses the daunting question of how a spiritual being navigates through a world obsessed with power, fame, and riches.

Currently, William is thinking about BLEEP 2, and is awaiting divine revelation.
