Marion Cotillard has revealed she learned Polish for her role in new film The Immigrant.
The Oscar-winner plays a Polish woman struggling with the realities of 1920s New York in James Gray's terse movie, and as large chucks of the dialogue are in Polish, she studied the language for the part.
Speaking at the Cannes Film Festival, Marion said learning the language spurred her on artistically.
"I ... create characters that have their own approach, their own physical language," said the French star.
"When you have a different language to learn, it somehow helps to create that."
The drama was filmed at Ellis Island in New York, where millions of immigrants arrived from Europe in search of a better life.
