"Hollywood" makes the characters more "sympathetic", better dressed, and better looking in gangster films,
but they very often capture the personalities and body language pretty accurately, when compared to people I've known.

Chicago is where I grew up. When "Back Home" was referenced in the film, they were talking about Chicago.
