Actor Léa Seydoux, who is best known for films like Inglourious Basterds, Midnight in Paris and Robin Hood, is set to star in an upcoming film titled The Unknown. The film will be directed by Arthur Harari, who co-wrote the Oscar-flick Anatomy of a Fall. 

Further details about the film are still under wraps. However, it is said that the film is a mix of fantasy, investigation and melodrama. 

The film is produced by Paris-based Bathysphere and is scheduled for completion in the first half of 2026. 

Meanwhile, Seydoux, who was last seen in Dune: Part Two, has a slew of films in the pipeline, including Silent Friend and Camere Separate, among others.
