The news, initially reported by Allociné, confirms Nighy's addition to what promises to be a gripping and atmospheric narrative. While his specific role in Ascension remains under wraps, fans are eager to see the acclaimed actor bring his distinctive presence to Cuarón's vision, nearly two decades after his memorable turn as the tentacled captain of the Flying Dutchman.

Alfonso Cuarón, a filmmaker celebrated for his genre-spanning works like Gravity, Children of Men, and Roma, is venturing into the horror genre with Ascension. This series will be his second collaboration with Apple TV+, following the 2024 mini-series Disclaimer. Cuarón is not only directing but also co-writing the series alongside his brother, Carlos Cuarón, with whom he previously collaborated on the critically acclaimed film Y tu mamá también.

Ascension is an adaptation of Adam Nevill's unsettling novel, Last Days. The story centers on Rose, a tenacious documentarian and recently divorced mother. While adept at uncovering the truths of others, Rose struggles with her own denial. Her latest project leads her to investigate the Church of Ascension, a mysterious 20th-century cult. Initially finding an unexpected solace in its philosophical teachings, Rose's deep dive into the cult's history soon unearths a trove of terrifying secrets.

The series has also cast Caitríona Balfe, best known for her leading role in the popular historical drama Outlander, as the protagonist, Rose. Her involvement, alongside Nighy's, sets a high bar for the ensemble cast.

Currently in its early pre-production stages, Ascension has been a long-gestating project, with rumors of its development dating back to 2017. Given that production has only just begun, viewers should anticipate a significant wait before the series premieres. Industry observers suggest a release date no earlier than early 2028 on Apple TV+, with late 2027 already earmarked for another major series. This timeline underscores the meticulous approach Cuarón and his team are taking to bring Nevill's chilling narrative to the screen. The combination of Cuarón's directorial prowess, Nevill's source material, and a stellar cast led by Balfe and Nighy positions Ascension as a highly anticipated entry into the streaming landscape.
