Charlie Cox to star in 'The Ordained'

A “Boardwalk Empire” star is joining a CBS family drama.

Charlie Cox will play Tom in “The Ordained.” Tom is the son in a Kennedy- ish family leaving the priest hood to become a lawyer to keep his politician sister, the New York City mayor, from being assassinated.

Cox played Nucky’s right- hand man and Margaret’s love interest Owen on the popular HBO drama.

Tom is more than a little like John F. Kennedy Jr. He reportedly joined the priesthood partly to spite his authoritarian father.

Lisa Takeuchi Cullen will write the script for CBS Television Studios. Cullen will exec produce alongside Frank Marshall (“War Horse,” “The Bourne Legacy”), Larry Shuman (“Devious Maids”) and A.B. Fisher. RJ Cutler will write the pilot, and Robert Zotnowski will be a co- exec producer.

Nestor Serrano (“Act of Valor,” “24,” “Dexter”) will play a partner at Tom’s law firm whom Tom suspects is behind his sister’s assassination plot.

Cox also starred in “Stardust,” miniseries “Moby Dick” (he played Ishmael), and upcoming “Hello Carter.” He had a small part on “Downtown Abbey.”

Cox is represented by WME and United Agents.
