Hypothetical Casting

When someone involved in a fictional project makes a list of actors who would best represent a cast of fictional characters.

The purpose of a hypothetical cast may be to give the reader of a fictional work a better picture of how a character looks and acts. This is common practice for online virtual series and sometimes used by authors of commercially published works. It can also be part of a hypothetical discussion by fans of a work.
