Riley Keough is set to play professional gambler Gina Fiore in a new drama about high-stakes casino advantage play in development at HBO. The project, in development with Media Res, is written by Will Graham and will also be executive produced by Keough.
HBO’s Advantage Player to Explore Gina Fiore’s Casino Career
The series, called Advantage Player, is based on Fiore’s upcoming memoir, Advantage Player: Blackjack, Backrooms, and Beginnings. It is scheduled to be published on October 27, 2026 by Gillian Flynn Books, an imprint of Zando and Penguin Random House.
Fiore has made money from casinos for more than 20 years, using techniques based on skill, observation, and mathematics rather than conventional gambling luck. Her experience includes blackjack, card counting and other advantage-play methods that can help give experienced players an edge over the house.
She began her career as a blackjack dealer in a Las Vegas casino and became intrigued by players who seemed to beat the odds on a consistent basis. She then taught herself to count cards and learned a variety of other techniques, including hole-carding and edge sorting.
Over the years, Fiore has worked in many of the major gambling destinations, eventually putting together teams of advantage players. Their activities made millions of dollars but also required them to deal with casino surveillance, changing rules, and the possibility of being identified and excluded from properties.
Riley Keough and Will Graham Reunite for HBO’s Advantage Player
Fiore’s story also includes a legal battle over nearly $97,000 in cash. Fiore and fellow gambler Keith Gipson had money confiscated by federal agents during a 2006 stopover in Atlanta after the pair returned from Puerto Rico. Eventually, the dispute ended up in the US Supreme Court in a case about whether the Nevada courts had jurisdiction over the federal agent. In 2014, the justices held that Nevada was not the proper venue for the lawsuit because the agent’s actions had occurred in Georgia.
The TV adaptation has been in development for several years. Fiore originally contacted Keough, who had heard the gambler’s story on a podcast. Eventually, their collaboration expanded to include Graham, who had previously worked with Keough in Daisy Jones & the Six, as reported by Deadline. Both earned Emmy nominations for their work on that series.
Graham will write and serve as executive producer on Advantage Player. Keough and Gina Gammell will produce under their Felix Culpa banner, with Fiore also serving as executive producer.
There is no production schedule or premiere date yet. Meanwhile, Fiore’s memoir should shed more light on the oddball career that HBO’s upcoming drama is based on.
