Background
In February 2013, George R. R. Martin commented that he had been in discussions with HBO regarding a potential adaptation of his Dunk and Egg novellas. In March 2014, Martin expressed interest in adapting his Dunk and Egg stories for the screen, suggesting that they could serve as the basis for a film. In July 2015, HBO programming president Michael Lombardo remarked that there was "enormous storytelling to be mined" in a prequel to Game of Thrones. However, in April 2016, Lombardo clarified that no Game of Thrones spin-offs were in development at that time. Shortly thereafter, Martin suggested that the most "natural successor" to the series would be an adaptation of his Dunk and Egg stories, adding that his preferred format would be a "two-hour standalone television film" for each novella. In November 2016, HBO's then-new programming president Casey Bloys confirmed that preliminary discussions were underway regarding a prequel project. In May 2017, Martin stated that a Dunk and Egg television adaptation was not in development, explaining that while he would like to pursue the project, he preferred to wait until the novella series—three stories published at the time, with seven to eight more planned—was completed, in order to avoid a situation similar to Game of Thrones, in which the television series outpaced the source material. In July 2022, it was revealed that Martin had formally pitched a Dunk and Egg adaptation to HBO in 2016. The network ultimately declined the proposal in favor of another concept, The Dance of the Dragons, which later entered development as House of the Dragon.Ryan Condal, showrunner for House of the Dragon, explained in a 2020 interview that he participated in the first and last stages of the initial cycle of prequel proposals. In early 2016, he approached Martin to suggest a series based on Dunk & Egg, but Martin rejected the idea because he wanted to finish that saga first. For that reason, Condal's suggestion never became a formal proposal nor was it part of the group of projects that HBO initially evaluated and rejected. After that failed attempt, Condal returned to the process in 2019 to lead House of the Dragon. However, Martin offered a different version in a podcast with Condal in September 2021. There, he acknowledged that Dunk & Egg was among the two prequel proposals he originally presented to HBO, along with The Dance of the Dragons. According to Martin, HBO rejected Dunk & Egg and asked him for more alternatives, which led to four additional ideas. Shortly thereafter, Condal independently proposed to Martin a Dunk & Egg series without knowing that HBO had already scrapped the project. This crossover of versions confirms that Martin changed his stance over time and ended up considering Dunk & Egg as one of his two preferred options for a prequel series, along with The Dance of the Dragons.
Development
announced that it was developing a new television prequel series to Game of Thrones in January 2021. The series follows the adventures of Ser Duncan the Tall and a young Aegon V Targaryen, nicknamed Egg, and is based on the novellas by George R. R. Martin that constitute the Tales of Dunk and Egg, taking place 90 years before A Song of Ice and Fire. There were reports that Steven Conrad was hired to write for the series in November 2021. The series received an official order from HBO in April 2023. By then, Ira Parker, a writer on the first season of House of the Dragon, had already written the script for a pilot episode. According to Martin, the series' writers' room shut down during the 2023 Writers Guild of America strike. Casting began in October 2023 with plans to begin filming in 2024. By February 2024, Warner Bros. Discovery CEO David Zaslav confirmed that the series had begun pre-production and that Martin was serving as creator and executive producer.In May, Owen Harris was hired to direct the first three episodes of the series and serve as an executive producer, setting the tone for the series. That June, Sarah Adina Smith was announced to direct three of the six episodes of the first season. Dan Romer scored the series. In November 2025, ahead of the first season premiere, the series was renewed for a second season, which is expected to be released in 2027. In January 2026, Parker disclosed that Martin had provided him with outlines for twelve unpublished Dunk and Egg stories. According to Parker, HBO intends to adapt only the three novellas that have been officially published. Parker, however, envisions adapting all twelve stories, planning to release four initially, followed by four more a decade later, and the final four ten years thereafter.
