The untitled procedural tells the story of genetic scientist who learns he has a psychopath gene but uses it to help the FBI catch killers. The premise is based on the work of James Fallon, a University of California, Irvine professor who discovered he was genetically linked to string of serial murderers.
Mirren, who vacated his role as showrunner on CBS' Criminal Minds last season, will write the pilot.
Ryan also has a relationship with the network. He executive-produced The Unit, which ran for four seasons. His two most recent series, Fox's The Chicago Code and FX's Terriers, were canceled after one season despite critical praise.
