"The Conqueror," released in 1956, faced significant controversy due to its filming location near nuclear test sites in Nevada. Many cast members, including John Wayne, Susan Hayward, and director Dick Powell, later developed cancer, leading to speculation about radiation exposure. Susan Hayward and John Wayne both died of cancer, along with several other cast and crew members. The film's legacy is marred by these health issues, and it is often cited as a cautionary tale about the impact of environmental hazards on film production.

As of now, there has been no official announcement regarding a movie specifically focused on Aegon the Conqueror. However, Aegon and his conquest of Westeros are significant elements of the "Game of Thrones" universe, particularly explored in the "House of the Dragon" series, which delves into Targaryen history. Future adaptations or projects could potentially explore Aegon's story further, but any specific film plans remain unconfirmed. Keep an eye on news related to the franchise for updates.
