Ari Emanuel’s Roll the Calls: A Memoir, released September 22, is a 432-page account of a career that moved from Hollywood agency mailrooms into the leadership of a major sports and entertainment business. Written with J.R. Moehringer, the Pulitzer Prize-winning journalist who previously collaborated on memoirs by Prince Harry and Andre Agassi, the book follows the making of Emanuel’s professional reputation as closely as it follows the deals and companies associated with it.

That distinction matters. The central story is not simply a timeline of corporate expansion from CAA and ICM to Endeavor, WME, UFC and TKO Group Holdings. Emanuel also writes about dyslexia, anxiety, therapy, family, anger and the persistent need to compete. The result is framed as a business memoir with a more personal question running beneath it: what happens when the drive that helps build an empire does not provide a lasting sense of arrival?

Emanuel now serves as executive chair and CEO of TKO and executive chairman of WME Group. Roll the Calls traces the route to those roles, but it also treats achievement as something transient. Even after his ascent from mailroom employee to billionaire entertainment executive, the memoir says the satisfaction of a win does not stay for long.

What the title means in agency culture

The phrase “roll the calls” comes from an older agency-office routine: an assistant would arrange a succession of phone conversations, moving a representative from one call to the next. It is an apt title for a figure whose public image has long been shaped by speed, intensity and confrontation. Rather than invoking the glamour of a premiere or the polish of a boardroom, the title points to labor, scheduling and a working tempo in which the next negotiation is already waiting.

In practical terms, a talent agency represents clients and seeks opportunities, contracts and partnerships on their behalf. Emanuel’s career then expanded far beyond the narrow idea of an agent making deals for individual performers. The memoir’s corporate milestones show a shift toward a broader entertainment-and-sports operation: talent representation alongside sports properties, fashion and media-related business interests.

The book begins with Emanuel’s early experience at CAA and ICM, then moves to 1995, when he left ICM and co-founded Endeavor. Its later chapters cover Endeavor’s combination with William Morris in 2009, its acquisition of IMG in 2014 and the 2016 purchase of UFC, a deal valued at roughly $4 billion. UFC subsequently joined WWE under the TKO Group Holdings umbrella in 2023. Endeavor itself was taken private by Silver Lake in 2025.

Those events can sound like a list of transactions, but the sequence explains why Emanuel’s memoir reaches beyond conventional Hollywood-agent territory. A representative’s job centers on a client’s career; a corporate executive’s remit can involve companies, brands and sports leagues. Roll the Calls covers the transition between those worlds through one person’s account of the deals and disputes that accompanied it.

A dealmaking memoir that does not dodge temperament

Emanuel does not present business success as a clean victory lap. He recounts fights, feuds and grudges along with major career accomplishments, and links his combative professional character to lifelong struggles with dyslexia and to his upbringing in Chicago alongside his brothers Rahm and Zeke Emanuel. The book also discusses anxiety, therapy and family life.

Dyslexia is a learning difference that can affect reading and language processing. Its inclusion gives the memoir a personal dimension distinct from its corporate history. The book does not treat the subject as a minor obstacle placed neatly at the beginning of a success story; it sits within a broader self-portrait of someone who describes relentless motion, rage and competition as recurring forces.

That candidness is also central to the book’s tension. Emanuel is associated with enormous professional ambition, yet the memoir repeatedly returns to the limited durability of achievement. The point is not that success is absent. The career chronology plainly contains major successes. Instead, the account suggests that accomplishment and contentment are not automatically the same thing.

This is where the memoir may be most useful to readers interested in entertainment-business power rather than merely its celebrity anecdotes. It offers a reminder that institutions are built by people with habits, vulnerabilities and personal histories, not by balance sheets alone. That does not turn harshness or conflict into virtues. It does, however, make clear why a book about deals also spends so much time on emotion.

From Endeavor to TKO: the business path in the book

The major business developments covered in Roll the Calls form the backbone of Emanuel’s story:

  • 1995: Emanuel co-founded Endeavor after departing ICM.
  • 2009: Endeavor merged with the William Morris Agency.
  • 2014: Endeavor acquired IMG, a sports and fashion company.
  • 2016: Endeavor bought UFC in a transaction valued at about $4 billion.
  • 2023: UFC and WWE were brought together in the publicly traded TKO Group Holdings.
  • 2025: Silver Lake took Endeavor private.

TKO is especially significant because it places UFC and WWE under the same corporate umbrella. “Publicly traded” means a company’s shares are available for public market trading, while “taken private” describes a company moving out of public ownership. These terms matter because they signal different structures of ownership and corporate accountability, even if the memoir’s focus remains Emanuel’s experiences within those systems.

The broad arc is one of scale. Endeavor began as an upstart agency and became part of a much larger enterprise spanning entertainment and sports. Emanuel’s current executive positions at TKO and WME Group reflect that split: TKO is connected to the UFC-WWE arrangement, while WME Group carries the agency lineage. The memoir therefore documents not only the expansion of a company but the reshaping of what a powerful representative could become in modern entertainment.

Famous names, personal stakes and contested memories

The memoir includes a substantial cast of well-known figures. Emanuel recalls signing Oprah Winfrey; clashing with Jeffrey Katzenberg and Harvey Weinstein; dealing with Michael Ovitz; and working around the careers and projects of clients including Martin Scorsese and Mark Wahlberg. He also writes about dropping Donald Trump as a client after Trump entered the White House, and recounts encounters involving Barack Obama and Elon Musk.

These appearances are part of the appeal, but they should not obscure the book’s premise. A memoir is one person’s account of events, relationships and decisions. The presence of famous names can add texture and show the reach of a career, but it does not convert every recollection into a neutral institutional history. Readers looking for an inside view of how Emanuel understands his own choices will find that perspective; readers looking for a comprehensive accounting from every participant should recognize the form’s limits.

Among the more personal stories is an incident in which Emanuel was nearly struck by a truck in Los Angeles in the 1990s. He frames it as a turning point, one that strengthened his determination not to let fear make his decisions. The account fits the memoir’s larger portrait of urgency: moments of danger and doubt become part of a personal argument for movement rather than retreat.

There are lighter and stranger flashes, too. Emanuel revisits a near-confrontation between Larry David and Musk at his 2022 wedding to fashion designer Sarah Staudinger, and he discusses behind-the-scenes battles surrounding films including Scorsese’s The Departed. Such stories give the book the people-and-places energy readers might expect from an entertainment memoir, while the more inward material keeps it from functioning solely as a catalogue of famous encounters.

Why the ‘Ari Gold’ connection is only part of the story

Emanuel’s reputation helped inspire elements of Ari Gold, the foul-mouthed agent played by Jeremy Piven on HBO’s Entourage. It is an unavoidable pop-culture footnote, and it helps explain why Emanuel’s name carries meaning well outside professional agency circles.

But Roll the Calls appears interested in the gap between a persona and a person. The traits that are easiest to dramatize—volatility, verbal aggression and relentless competitiveness—are here placed beside dyslexia, anxiety, therapy and family. That does not erase the traits that made the fictional comparison feel recognizable. It makes the comparison insufficient as a complete description.

For pop-culture readers, that is the more compelling prospect. The agent caricature is familiar: a loud, unstoppable dealmaker defined by the next win. Emanuel’s memoir instead presents the cost of being unable to stop chasing that next win, and it places one of entertainment’s most visible business careers inside a more complicated self-assessment. The wider entertainment system has often rewarded people who can move quickly, make difficult calls and refuse to be intimidated. This account asks what those expectations can demand from the people who meet them.

That context also makes the title feel less like a nostalgic office expression and more like a statement of philosophy. Calls are rolled, conversations are lined up, and the work keeps advancing. Yet the memoir’s most revealing thread is that there is no obvious final call that resolves the pressure to keep going. For Emanuel, business expansion, celebrity access and professional power do not end the pursuit; they provide the setting in which that pursuit continues.

Readers following Hollywood’s changing business structure may also find useful context in the distinction between sponsorship and mentorship in Hollywood careers. Emanuel’s account, from a very different position of power, similarly highlights how access, advocacy and business decisions can affect whose work moves forward.
