Alien: Romulus actor Spike Fearn is the latest addition to the cast of Searchlight Pictures' Sweetsick. He joins lead actor Cate Blanchett in the film, which marks the directorial debut of Alice Birch.

Sweetsick revolves around a mercurial woman (Blanchett) with a strange and piercing gift – the ability to see what others most intimately need, often at great personal cost – who sets out on a journey home. The upcoming film is set for production soon in the UK and Greece. Additional casting will also be announced soon.

Alice Birch is best known for writing Lady Macbeth and adapting Sally Rooney’s novels Normal People and Conversations with Friends into acclaimed miniseries. Birch is also the writer for the upcoming film.

Searchlight Pictures is producing the film. Tessa Ross, Juliette Howell, Theo Barrowclough and Lee Groombridge are also backing the film, while Film4 serves as the executive producer and is co-financing the project. The project is being overseen by Searchlight's VP of Development & Production Pete Spencer and Creative Executive Cameron Chidsey, who report to Production & Development Heads Katie Goodson-Thomas and DanTram Nguyen.

Apart from Sweetsick, Fearn will also appear in James L Brooks' Ella McCay, set for release on December 12, and Alicia MacDonald's Finding Emily from Focus Features.
