The film is a sequel of
Red, White & Royal Blue (2023), which itself was based on the 2019 novel
Red, White & Royal Blue by
Casey McQuiston. The 2023 film was an enemies to lovers romance between the fictional
third in line to the throne of the United Kingdom, Prince Henry (Galitzine), and the son of the fictional
President of the United States Ellen Claremont (
Uma Thurman), Alex Claremont-Diaz (Zakhar Perez), as they navigate their private lives with their public ones as figureheads for their respective countries. López revealed the news at a Q&A after a promotional screening of the first film, followed by a teaser image with the caption "fancy another slice?". Unlike the first film,
Red, White & Royal Wedding does not have a book it will be directly adapted from as the original novel was a standalone work. ==Production==
