Saoirse Ronan will reunite with Timothée Chalamet and director Wes Anderson for post-WWII film, The French Dispatch.
The upcoming movie is set in the 1950s and follows a group of journalists at an American newspaper bureau in Paris, though filming is currently taking place in Angouleme in South West France.
It has been described as "a love letter to journalists set at an outpost of an American newspaper in 20th-century Paris and centers on three storylines."
Ronan, who worked with Anderson on 2014's The Grand Budapest Hotel and with Chalamet on last year's Lady Bird, let the news of her casting in the historic drama slip during a recent video interview for her next movie, Mary Queen of Scots.
When asked by movie website GoldDerby if she is reuniting with the 49-year-old filmmaker, she said: ''Yeah, in the spring.''
Before asking: ''Has that (casting) been released? Well it has now."
The 24-year-old Golden Globe winner joins a star-studded ensemble along with Benicio del Toro, Jeffrey Wright and the director's frequent collaborators Bill Murray, TIlda Swinton and Frances McDormand.
Anderson is writing the film as well as directing, while Scott Rudin is on board to produce.
Ronan can next be seen playing the titular role in Mary Queen of Scots opposite Margot Robbie as Mary's cousin Queen Elizabeth I in the drama biopic, which focuses on the feud between England and Scotland in 1569.
Mary Queen of Scots hits Irish cinemas on January 18, 2019.
