Ben Affleck has directed three movies: Gone Baby Gone, The Town, and Argo. Titus Welliver was in all three. I believe he played Ben Affleck.
Now the dynamic duo is back at it again. According to The Wrap, Welliver has just joined the cast of Live by Night as a big mob boss type guy. His character will supply a mentor role to Affleck’s Joe Coughlin, the son of a police captain who enters the organized crime world, which typically lives soon after dusk.
The cast also includes Sienna Miller, Zoe Saldana, Anthony Michael Hall, Chris Cooper, and Scott Eastwood. Live by Night comes out in 2017, and will likely be the last non-Batman thing Affleck does for the rest of his life.
