Joy – the new film starring Jennifer Lawrence – is a “very feminist film”, according to her co-star Isabella Rossellini.

The 63-year-old actress, daughter of Italian film director Roberto Rossellini and actress Ingrid Bergman, said it was “very modern to show a woman solely focused on her career”.

Jennifer plays working mother Joy Mangano, the inventor of the QVC shopping channel’s best-selling Miracle Mop, over four decades.

Describing Joy as “a very feminist film”, Isabella told The Sunday Times Style: “Every time we see a film about a woman who wants a career, invariable there must also be love. Or it’s the man, her Prince Charming, who helps her make it. I thought that it was very modern to show a woman solely focused on her career.”

She added that she sees the story as a battle cry for working mothers.

The mother-of-two said: “The biggest problem for women has always been how to reconcile being a mother with your career.

“Yes, women can enter the man’s world now, but for a woman who wants to direct films, for example, the hours make it impossible if you have children.

“Many women with the desire to work with narratives give up and write a book instead.”

In the film, Isabella plays Trudy, a wealthy widow who gives Mangano money to help her business.

She added: “Joy is actually a study of women and independence. I always wanted to work and have my own money, because if you had to ask your husband or your dad for money, then you wouldn’t be free.”

The UK release date for Joy is January 1.
