Isabelle Huppert has been named actress of the year at the Critics' Circle Film Awards for her role as an ordinary woman in Things To Come.
She said the award "cast a light on a film that speaks honestly about a woman's life in a realistic way - not fantasy, just how it is".
The 63-year-old French star plays Natalie Chazeaux, a philosophy teacher faced with the death of her mother, getting fired from her job and her husband's affair.
Huppert was also presented with the prize for excellence in cinema at the awards' 37th ceremony at The May Fair Hotel in central London.
She told the Press Association: "The film is very telling for women as well as men and it is doing very well in other countries, which is an indication that more films like this should be being made.
"Things need to be said about women's lives in general and cinema has that power."
Her recognition comes a day after hundreds of thousands of people turned out in cities across the world to protest against comments made by new US president Donald Trump about women.
Moonlight star Naomie Harris, who picked up an award for best supporting actress at the event, said she "started crying" after hearing about the success of the Women's March.
She told the Press Association: "I was so moved by the level of solidarity and community, of men and women marching together and making sure their voices were heard.
"It's such a beautiful thing, it's overwhelming - the numbers are astonishing."
She also said while she faced one of the toughest challenges of her career in the Barry Jenkins film, she would "love" to reprise her role as Miss Moneypenny in a new James Bond film.
