The Irish star's busy schedule meant that she didn't have time to appear in the Greta Gerwig production.
Hiya Saoirse, wanna go for a ride? Nope, unfortunately not. Saoirse Ronan won't be making a guest appearance in the 'Barbie' movie after all, according to the 28-year-old.
Earlier this year there were rumours of Ronan joining the cast of the comedy film in a smaller role, expected to appear as another version of the titular Mattel toy (who will be played by Margot Robbie). The movie comes from director Greta Gerwig, whom she has worked with on 'Little Women' and 'Lady Bird', so the rumours seemed legit.
And it turns out they were true - but it never went to plan. Ronan told PEOPLE she was "gutted" that she couldn't be a part of the film: "I was supposed to do a cameo because I live in London and they were [filming] there. There was a whole character I was going to play — another Barbie. I was gutted I couldn't do it."
But with 'Barbie' having a release date of July 2023, she's quietly confident that she might still make a last-minute cameo appearance - if there's any extra shots to do back in London.
She's been texting Robbie and Gerwig, just in case: "I have texted Margot and Greta and I'm like, 'If you're doing any pick-up [shots], maybe I can just walk through the background?'"
Saoirse Ronan missed out on 'Barbie' because she was filming an upcoming drama called 'The Outrun' which was filming in Scotland. From director Nora Fingscheidt ('The Unforgivable'), the film is based on the book of the same name by Amy Liptrot.
Around the same time as Ronan's supposed casting in 'Barbie', pop star Dua Lipa was also rumoured to have joined the cast. This, however, still remains unconfirmed.
Either way, there's a shed load of talent involved in the production, including Ryan Gosling as Ken, Will Ferrell as the CEO of a toy company, plus America Ferrera, Kate McKinnon, Simu Liu, Ncuti Gatwa, Emma Mackey, Alexandra Shipp, Hari Nef, Issa Rae, Kingsley Ben-Adir, Ritu Arya, Rhea Perlman, Ariana Greenblatt, Sharon Rooney, Scott Evans, Ana Cruz Kayne, Jamie Demetriou, Emerald Fennell, Connor Swindells, and Michael Cera.
Whoof - Barbie's going to need a bigger beach house for all of this talent.
Catch Saoirse Ronan in 'See How They Run' alongside Sam Rockwell, Harris Dickinson, Adrien Brody and many more, which is in cinemas now.
