The Sony-produced project, which has been granted a put pilot commitment at the network, centers on a genetic scientist who uses his own psychopath gene to assist the FBI. The plot line is inspired by the real life story of UC Irvine professor/scientist James Fallon, who discovered he, too, was a psychopath with relations to a series of serial killers.

Mirren, who until recently served as a co-showrunner on Minds, will write and executive produce, with Ryan attached as a writer. For Ryan, who has struggled of late with critically-acclaimed cop dramas including FX's Terriers and Fox's Chicago Code, a CBS procedural would seem a more reliable next step. 

Mirren and Ryan, who have an overall deal at Sony, are both repped by WME.
