Rensin (coauthor, Don't Stand Too Close to a Naked Man) captures the ambition, manipulative plotting and hustler mentality of a few Hollywood mailroom employees in this series of raunchy, realistic interviews with some top agents who started out in the mailroom. As with any entry-level gig, "the hours are long, the pay... abysmal." Star mailroom grads from the William Morris Agency, Creative Artists Agency, ICM and others voice conflicting views, making Rensin's book an uncompromisingly truthful tell-all of what it takes to make it in the movie biz. William Morris's Norman Brokaw recalls, "I made it a point to develop relationships early on," while Bernie Brillstein's a bit more blunt: "I kissed ass." Most of the agents admit opening up private correspondence and packages, insisting, "everybody did it." Rensin also exposes affairs with secretaries to learn company secrets, fights over use of phones that led to wrestling matches, and homophobia. Sam Haskell, William Morris's worldwide head of television, offers a different take: "Your primary power is your character and your integrity." Rensin furnishes fresh anecdotes about an embarrassed novice who didn't recognize Judy Garland, or another who believed in Marilyn Monroe despite a casting specialist calling her "just another blonde." Clashing views of Mike Ovitz, from "a superb leader" to someone who preferred "style over content" and to whom "appearances were everything," help explain Ovitz's meteoric rise and massive collapse. Most notably, Rensin shows that the road from mailroom to mogul is a rough one. The stories are amusing, intriguing and sometimes horrifying, but Rensin, to his credit, never dilutes sordid details.
