How Old Every Major Character Is In XO, Kitty

Netflix's "XO, Kitty" spans a significant age gap between its cast and characters, creating an intentional disconnect between performer and role. Anna Cathcart, who headlines the spinoff from "To All the Boys I've Loved Before," plays the titular Kitty Song Covey as a high school senior, though Cathcart herself is considerably older than the character she portrays.

The ensemble cast follows the familiar pattern of prestige teen television, with actors in their twenties and thirties inhabiting roles as teenage students. This practice remains standard across streaming and broadcast networks, where studios prioritize experienced performers over authenticity of age. Networks justify the approach through labor laws and the demands of long production schedules that require adult cast members capable of handling grueling shoot days.

"XO, Kitty" frames itself as a companion piece to the "To All the Boys" film trilogy, which built its identity around the coming-of-age romance and family dynamics of its younger protagonists. The streaming series expands that universe into a competitive international school setting, introducing new characters while maintaining tonal consistency with the films. Cathcart's return as Kitty anchors the series and ensures continuity with the established fanbase who followed her character through three films.

The show's setting at a prestigious boarding school in South Korea allows the narrative to explore fish-out-of-water scenarios and cultural exchange themes. That framework justifies both the younger character ages and the adult casting choices, as the show positions itself as aspirational entertainment aimed at teen and young adult viewers while maintaining the production flexibility that older actors provide.

This casting approach reflects larger industry norms rather than any specific creative choice by "XO, Kitty's" producers. Major networks from the CW to Disney Channel to Netflix consistently cast actors several years older than their characters. The practice proves especially prevalent in teen-focused properties
