Kate Winslet struggled to portray the breakdown of a relationship in new TV mini-series Mildred Pierce, because the scenes reminded her of splitting from husband Sam Mendes.
The Titanic star announced the end of her seven-year marriage to the American Beauty director last year (10).
She admits she found it hard to shoot emotional scenes in her upcoming U.S. TV drama, and often felt numb when she used her own heartbreak to help act out the part.
She tells Britain's Daily Express, "It was tough. There were moments like that one where I was using things from my own life in my performance. There were days when I'd almost feel comatose."
