Exclusive: Sky Yang, Sean Kaufman Join 'Tomorrow' Film

July 24, 2026 - LOS ANGELES - The film adaptation of Gabrielle Zevin’s best-selling novel “Tomorrow, and Tomorrow, and Tomorrow” has added two rising stars to its ensemble, with Last Days actor Sky Yang and The Summer I Turned Pretty regular Sean Kaufman joining the cast in undisclosed roles. The production, which has been quietly assembling talent since securing the rights to the beloved 2022 book, is now rounding out key supporting players as cameras prepare to roll.

Yang, who broke out with a powerful performance in the A24 crime drama Last Days and has been closely associated with the Tomb Raider franchise, brings a résumé that balances indie credibility with blockbuster visibility. His casting signals the project’s ambition to attract both prestige-minded audiences and younger viewers drawn to the novel’s devoted fanbase. Kaufman, best known for his recurring role as Steven Conklin on the hit Amazon Prime series The Summer I Turned Pretty and for his work in Firefly Lane, adds a familiar face for Gen Z and YA audiences who have propelled the source material onto bestseller lists year after year.

While the production has not confirmed which characters Yang and Kaufman will play, the novel - a sprawling, decades-spanning story about friendship, love, and the video game industry - features a large ensemble. The book centers on two childhood friends, Sam and Sadie, who reunite in college and create a blockbuster video game together, then navigate the complexities of creative partnership across adulthood. Supporting roles include Marx, Sam’s charismatic roommate and eventual business partner, as well as several game developers, professors, and friends who populate the characters’ world from Cambridge, Massachusetts to Los Angeles and beyond.

The film adaptation has been in development since early 2023, following a heated bidding war among studios for the rights to Zevin’s novel, which was one of the most acclaimed literary works of its year. Tomorrow, and Tomorrow, and Tomorrow spent months on The New York Times bestseller list and was a finalist for several major awards, praised for its nuanced depiction of ambition, disability, and the tension between creative collaboration and personal intimacy. The book’s narrative structure, which jumps across years and between point-of-view characters, presents both a challenge and an opportunity for screen adaptation.

Little is known about the director or the exact production timeline, but the addition of Yang and Kaufman suggests the project is moving toward a full casting announcement. Yang, who first gained attention in the independent circuit before landing a role in the Tomb Raider universe, has been selective about his projects since his breakout turn in Last Days. His choice to join this ensemble indicates the script’s strength, as the actor has expressed interest in character-driven stories that explore psychological depth.

Kaufman, meanwhile, has become a fixture in young adult adaptations, and his casting underscores the project’s intent to attract the demographic that made The Summer I Turned Pretty a streaming phenomenon. That series, based on Jenny Han’s novels, has made Kaufman a familiar presence to millions of viewers, and his move to a major literary adaptation positions him for wider recognition.

Neither representatives for the actors nor the production have commented beyond confirming the casting. The project remains without a scheduled release date, and details on the remainder of the cast - particularly the lead roles of Sam and Sadie - have yet to be announced. Given the book’s devoted readership, any casting news is likely to draw intense scrutiny, especially as fans debate which actors could capture the nuanced chemistry at the story’s core.

What is clear is that “Tomorrow, and Tomorrow, and Tomorrow” is assembling a cast that balances emerging talent with recognized performers, a strategy common for adaptations aiming to satisfy existing fans while courting new audiences. The addition of Yang and Kaufman represents the project’s first public movement since its initial announcement, and suggests that the production is shifting from development into active pre-production.

The novel’s themes - the nature of creativity, the cost of artistic ambition, the wounds of childhood friendship - have already resonated deeply in literary circles. Whether the film can capture the same emotional resonance, or will need to compress and reshape the sprawling story, remains to be seen. For now, the inclusion of two rising stars signals that the film is building from a foundation of strong young performers, a choice that could pay off if the leads are cast with equal care.

As the project moves forward, the entertainment industry will be watching closely. Zevin’s novel was one of the most talked-about books of the decade, and the film adaptation carries high expectations. With Yang and Kaufman now attached, that pressure only grows - and so does the anticipation.
