One chapter of Morrell's writing book is on his experiences in Hollywood. He mentions a certain producer (not by name) who invited him to sit in on his office day to see what it was like. It consisted mostly of not taking people's calls, then calling someone else to see if they knew what the caller may have wanted.
Apparently in Hollywood, the studio executives almost never actually read a book. They read the "coverage," which is a 1 to 2 page summary of the book done by someone other than the writer. Morrell told of a studio exec who put his arm around Pat Conroy one time and told him what a great writer he was. "The coverage on your book moved me to tears," the Exec said.
Morrell's primary advice? Be careful as a newbie writer dealing with Hollywood or they will eat you alive.
