It’s been a long road, but the live-actionMobile Suit Gundammovie is finally coming together. Originally announced in 2018 as a partnership between Legendary Pictures and Netflix,theGundammoviewas restructured in 2025 as a joint production between Legendary and Bandai Namco after Netflix exited the collaboration. Details about the story and crew for this adaptation of the classic mecha anime franchise remain scarce. What we do know is that Jim Mickle, known for his work onSweet Tooth, is set to write and direct—but until now, that’s been just about all we’ve heard.
Things changed earlier this week when it wasreported that actress Sydney Sweeney—known for her roles inMadame Web andImmaculate—is in final talks to star in theGundammovie. The news has sent shockwaves through theGundamfandom worldwide, sparking a flurry of speculation about which role she might take on. While no official details about the plot or characters have been revealed,one classicGundamcharacter seems like a natural fit for Sweeney: Sayla Mass.
Who Is Sayla Mass? A Classic Character With Deep Roots
Sayla Enjoys An Enduring Popularity Across The Gundam Universe
Sayla Mass is a character who dates all the way back to the very first episode ofMobile Suit Gundamin 1979 and plays a key role in the original One Year War storyline. She serves as both a communications and medical officer aboard the Earth Federation’s assault carrier, White Base. Sayla is also secretly the younger sister of series antagonist Char Aznable, and her family history is deeply entwined with the very conflict she’s fighting in.
While technically a supporting character,Sayla’s arc is rich with drama and emotional moments. Fans have long admired her quiet strength and steady presence amid the chaos of war.
Sayla’s popularity has remained high throughoutGundam’s long history, which now includes nearly 50 official anime productions. Later series and side stories have continued to explore her life both before and after the original series, maintaining strong interest in her character among fans. Notable examples includeMobile Suit Gundam: The Origin(2015–2018), which depicts her early years, andMobile Suit Gundam 0083: Stardust Memory(1991–1992), where she briefly appears in a senior Earth Federation role.
Could Sydney Sweeney Really Be Sayla? Here’s Why Some Think So
Sweeney’s Role Is Still A Mystery
So why are some betting on Sydney Sweeney stepping into the role of Sayla Mass?For starters, she seems like a strong fit for the character in terms of presence and tone—even if there’s a notable age gap, as Sweeney is 27 while Sayla is canonically 17 whenMobile Suit Gundambegins. Physically, she shares some of Sayla’s key traits, starting with her hair: she’s blonde, much like Sayla herself. And it’s easy to see her in Sayla’s iconic white and pale red Earth Federation uniform.
If Gundam’s Hollywood Movie Wants to Hit, It Needs to Make One Thing Clear
With decades of history in the Universal Century, Gundam’s live-action film must honor its legacy while reaching new audiences.
Still, with no confirmed story or setting for theLegendaryGundammovie, Sweeney could just as easily be playing a brand-new character. The One Year War might not factor in at all. With so many timelines and stories to draw from, anything’s possible. Either way, fans are curious—and hopeful—to see howGundammakes the leap to live action and who might join the cast next.
