Andy Garcia had previously signed on to play Vince Rizzo, "a Bronx prison official who realizes that an inmate (Steven Strait) is his secret love child. His efforts to become his guardian lead to comic complications." Marguiles is taking on the role of Garcia's wife, and it seems that the man is also looking to become an actor because Arkin will play a teacher in the acting class, and Mortimer will be a fellow student he becomes friends with. Garcia's real-life daughter Dominik Garcia-Lorido will play his daughter, and Ezra Miller has also nabbed an undisclosed part.
I really don't know how all of this acting works into prison officials and long-lost bad boy sons, but we should see soon enough. The film went into production this week in the Bronx.
