She was highly acclaimed and awarded for her lead performances in The Immigrant (2013) and Two Days, One Night (2014), receiving a second Academy Award nomination for Best Actress for the latter, which was also her second nomination for a French-language film and the first time an actor was nominated for a Belgian film.

In the drama, Cotillard portrayed twins of completely opposite characters, Lucie and Marie, and she was nominated for a César Award for Most Promising Actress for her performances.
