Dunstan was born in Boise, Idaho, and raised from the age of five in Macomb, Illinois. He met writing partner Patrick Melton while studying at the University of Iowa. The duo's first collaboration, FEAST, was produced for season three of PROJECT GREENLIGHT. The FEAST films became a trilogy for Dimension.
Dunstan and Melton turned to more serious horror fare in their collaboration on the SAW franchise for Lionsgate. Melton and Dunstan co-wrote SAW IV, SAW V, SAW VI and SAW 3D for the studio. They also did an un-credited rewrite on another 3-D chiller, MY BLOODY VALENTINE.
The writing duo recently completed adapting their first novel, BLACKLIGHT, into a script for producer Michael De Luca. Summer 2013 sees the release of Guillermo Del Toro's PACIFIC RIM, on which Melton and Dunstan contributed a production polish for Warner Bros. They have also commenced writing the sci-fi adventure RISE for the studio and are adapting the popular video game God of War for Universal.
Currently, Dunstan spends every waking moment being grateful.
