The 40-minute movie by Jay Kensinger, first released in 2002, is an adaptation of Paul Levinson's novelette "The Chronology Protection Case" - inspired by Steven Hawking's "chronology protection conjecture" - and first published in Analog Magazine in September 1995. The novelette was a finalist for the Nebula and Sturgeon Awards, reprinted five times - including in the currently best-selling Mammoth Book of Time Travel - and made into an Edgar nominated radio play. The novelette is cited in Paul J. Nahin's A Writer's Guide to the Real Science of Plausible Time Travel as the only recent treatment in science fiction of Hawking's conjecture.
Kensinger directed, produced, wrote, and plays the role of Dr. Phil D'Amato in the movie. D'Amato has appeared in two other novelettes by Levinson - "The Copyright Notice Case' and "The Mendelian Lamp Case" - and in three novels by Levinson, The Silk Code, The Consciousness Plague, and The Pixel Eye.
The extended ending in the 2013 release of the movie brings the story forward from 2002 to 2012, and was written by Levinson and Kensinger. The 2002 release was shown at science fiction conventions around the east coast, including I-Con and Philcon.
