“Sons of Anarchy” thesp Patrick St. Esprit has joined Errol Flynn biopic “The Last of Robin Hood” alongside Kevin Kline, Dakota Fanning and Susan Sarandon.

Christine Vachon (“Boys Don’t Cry”) and Pam Koffler (“At Any Price”) are producing for Killer Films, with “Quinceanera” helmers Richard Glatzer and Wash Westmoreland directing from their original screenplay. “Robin Hood” is shooting soon in Atlanta.

Kline is starring as Flynn in the film, set in the actor’s last days before he died of a heart attack at age 50 in 1959. Pic follows his relationship with 17 year-old actress Beverly Aadland (played by Fanning), an actress who came to love Flynn after she allegedly seduced by him when she was 15.

Sarandon and St. Esprit are portraying Aadland’s parents with St. Esprit playing a down-to-earth engineer baffled by his wife’s obsession with Hollywood stardom and angered when he discovers his daughter’s affair.

St. Esprit has been also shooting Lionsgate’s “The Hunger Games: Catching Fire” as the Head Peacekeeper of District 12. His credits include “We Were Soldiers,” “United 93,” “Green Zone” and “Super 8” along with episodes of “Rizzoli & Isles” and “NCIS: Los Angeles.”
