EXCLUSIVE: Casey Affleck is poised to join the cast of Out of the Furnace, the Scott Cooper-directed revenge thriller that Relativity Media will put into production later this year with Christian Bale starring. The script, which originated as a Brad Ingelsby spec that sold with Leonardo DiCaprio and Ridley Scott attached in 2008, is finally coming together. Bale plays a guy who’s released from prison and wants only to get his life back and marry his gal. All that changes when his brother is murdered, and the mission becomes revenge. Affleck, I hear, will play the unfortunate brother. Scott Free and Appian Way are producing, Brooklyn Weaver is exec producer. Affleck is repped by WME and Brillstein Entertainment Partners.
