Are there some kind of common or standard rules for naming characters in movies?
I am especially asking with with fictional movies in mind that depict scenarios that are based on more or less realistic universes.
Example given: "Designated Survivor". Is there a in- or out-of-universe reason for the names of the character like Mike Ritter, Tom Kirkland, Aaron Shore, Hookstraten or even Bowman?
Should such names help tell part of the story? To me they seem just erratic. I am living in Europe, so I could miss some specifics of those names.
