‘Red, White & Royal Blue’ Author Casey McQuiston Says Next Screen Installment Will Be “A Couple Degrees Spicier”

Casey McQuiston, the author and co-writer behind Red, White & Royal Blue and its sequel, teased that the next installment in the Alex and Prince Henry love story will be “a couple degrees spicier” than the original movie, while also acknowledging there are creative guardrails and that she is hoping to “not get in trouble.” McQuiston made the remarks during Prime Video’s Obsessed Fest, according to Deadline, as organizers discussed what fans can expect from the forthcoming screen chapter and how the narrative is evolving.

McQuiston’s comments focused on the tone shift that audiences may see as the story moves beyond the first film’s big milestones and toward the “next chapter” referenced in marketing for the sequel adaptation. Deadline reported that McQuiston, who worked on the sequel alongside fellow writer/creative collaborators, suggested the romance will intensify, framing the change as a gradual escalation rather than a reinvention of the franchise’s core dynamic.

At the same event, Deadline said McQuiston also alluded to the challenge of previewing details publicly, saying she hopes her tease does not draw criticism or consequences. The remarks connect with the practical reality of franchise releases, where studios and streamers often balance fan engagement and promotion with keeping key plot points controlled as production and release timelines develop.

Obsessed Fest is a Prime Video-focused convening centered on audience enthusiasm for streaming series and films, and McQuiston’s segment underscored how the streamer is using talent appearances to sustain attention between announcements. In this case, the author’s visible role in the storytelling pipeline, including work on the sequel material, positioned her as a bridge between the books and the screen adaptations for viewers tracking how the narrative will translate.

The franchise’s fan base has followed not only the characters’ relationship arc but also how the adaptations handle intimacy, language, and the pace of plot reveals. McQuiston’s “spicier” characterization, as reported by Deadline, indicates an emphasis on hotter romantic beats, while the “hope I don’t get in trouble” framing suggests she was mindful of what she could say onstage rather than offering a detailed, spoiler-heavy walkthrough.

Deadline’s report also places the teasing in the context of the movie coming next, describing it as the sequel’s “next” chapter rather than a standalone project. That distinction matters for audiences who are trying to map the storyline continuity and understand whether the adaptation will follow the same character trajectory and emotional rhythms established in Red, White & Royal Blue.
