of the current script to agents for what is known as coverage. Coverage is when a script yet to be cast is read, summarized into a one-pager, and a brief set of character descriptions established. At this time, if an agency agrees to give coverage to a film, they will submit a list of ideas to the casting directors of actors available, capable, and in the price range of the film. Also, casting directors create their own idea lists and can "check avails" or call the actor representation to see if they are available and interested in taking on potential projects. If an idea that is generated from a casting director and a subsequent avail check or from an agent's recommendation is "approved" by the director, producers, and financiers (or studio), the casting director sends out what is called an "offer". The offer, usually contains a letter to the actor's representative explaining the role in question, a copy of the script, why the actor has been selected, the length of time commitment, the approximate start date of filming, the filming location, and the proposed salary offering. If the actor does not respond to the material or for whatever reason cannot accept the job, they respond to casting with what is called a "pass." If they accept the offer, the agent engages the casting director and a deal memo is sent from casting to the representative. It is at this time when negotiations between agency and production happen to finalize any deal points before the entertainment lawyers step in and draw up the attachment contracts. If this process happens very early on in the development of a movie but the official shoot dates and details are not yet known, a Letter of Intent or "LOI" is drafted, to indicate, if and when the project is "green lit" or begins active production, the actor is already hired to portray that particular role. After the attachment phase is complete (which depends on many factors, including financial backers, studio heads, availability of other above-the-line personnel), the physical auditions begin for all of the remaining roles. During this time, depending on the budget of the film, they could have what is called "pre-screens" where the actor auditions only for a casting director (or associate) to see if they are right for the material. After pre-screens would be a "director session". During this time the actor
