Chris Cooper has signed on for Ben Affleck’s adaptation of “Live by Night.”

Cooper joins Chris Messina, Elle Fanning, Sienna Miller and Zoe Saldana in the cast, with Affleck also toplining and producing along with Jennifer Todd through their Pearl Street banner, as well as Leonardo DiCaprio and Jennifer Davisson Killoran through their Appian Way banner.

Based on the Dennis Lehane novel, the Prohibition-set drama examines the world of organized crime.

Cooper has been eyed to star for some time, but delays in production due to Affleck’s commitments to “Gone Girl” and “Batman v Superman: Dawn of Justice” forced the studio to hold off on handing out other offers. Variety first reported the greenlight was given in July for the pic’s November start, and offers have gone out since then

Cooper and Affleck first worked together in Affleck’s “The Town,” in which he appeared as Affleck’s father. Sources say Cooper will play a Florida sheriff who has a run-in with Affleck’s character in the film.

Cooper was last seen in Fox Searchlight’s “Demolition,” which premiered at Toronto and bows next April. He also stars in the Hulu limited series “11/22/63,” premiering in November.

Cooper is repped by Untitled Entertainment.
