Cargill wrote for Ain't it Cool News for nearly 10 years under the pseudonym Massawyrm, as well as serving as a staff writer for Film.com and Hollywood.com. He appears as the animated character Carlyle on spill.com, where he also hosts a featured podcast. His first screenplay, the critically acclaimed SINISTER, was co-written and directed by Scott Derrickson and starred Ethan Hawke. He co-wrote the screenplay for Marvel's DOCTOR STRANGE.
Cargill offers a fascinating and intellectually engaging take on the venerable robots-versus-humans theme. An absolute must-read. [An] equally thrilling and moving blend of action and ideas. . . . Admirers of thoughtful hard sci-fi will hope Cargill continues to flesh out this bleak but brilliant world. Veteran SF fans will spot shades of Isaac Asimov, whose Laws of Robotics appear early on, as well as the novel's dedicatee, Harlan Ellison, but Cargill never lets homage stand in the way of good storytelling. . . A delightful read. Cargill does an excellent job of infusing all of his characters, robot and human alike, with personality and pathos. . . . If you're looking for something to read on the beach this summer that has action and mayhem, but also some existential doubt and emotional heft, you can't go wrong with Day Zero.
