Homeland's Rupert Friend and Harry Potter star Evanna Lynch are to play the lead roles in James & Lucia, a new film about author James Joyce's relationship with his only daughter.

US entertainment trade publication Deadline, which first reported the actors' casting, said James & Lucia is the new film from writer-director Robert Mullan (Mad to be Normal).

"Based on the final decade of Joyce's life, firstly in Paris then in Zurich, the film highlights his struggles with his fading eyesight and, centrally, his attempts to protect his beloved daughter, Lucia," said Deadline.

Lucia, a professional dancer, was diagnosed as schizophrenic in the 1930s and institutionalised in Switzerland and the UK. She died aged 75 in St Andrew's Hospital, Northampton in 1982, having been a patient there for over 30 years.

James Joyce died in Zurich in 1941 at the age of 58. His wife and Lucia's mother, Nora Barnacle, died in Zurich in 1951 at the age of 67.

"James & Lucia is less a story about literary genius and more about a father's deep love for his daughter - as he protects her from unsuitable lovers, enthusiastic psychiatrists and, most importantly, her own demons," said writer-director Mullan.

Filming is due to begin in Italy in March.
