Hollywood's leading females were out in force yesterday as tens of thousands of women and men demonstrated in cities across the globe.

Returning for its second year, the Women's March began in 2017 in opposition to the newly elected Donald Trump.

Reproductive health and Trump's anti-abortion stance were just some of the issues being protested at this year's event, and while the tone of the demonstrations remained highly political, recent allegations of rampant sexual harassment in the entertainment industry were also a topic of discussion.

Speaking to crowds at the Women's March rally in Los Angeles, actress Scarlett Johansson gave a powerful speech on behalf of the Time's Up campaign – during which, she called out James Franco, who had claimed to be a supporter of the movement despite being accused of sexual misconduct by five different women.

“How could a person publicly stand by an organisation that helps to provide support for victims of sexual assault while privately preying on people who have no power?” she asked the crowd.

Adding: “I want my pin back, by the way,” on reference to the Time's Up pin worn by Franco on the Golden Globes red carpet earlier this month.

While she did not mention him by name, a representative for the star later confirmed to the Los Angeles Times that she was indeed referring to the Disaster Artist director.

James has denied all allegations of wrongdoing, claiming that he prides himself on being able to take responsibility for his actions.

Speaking on The Late Show with Stephen Colbert, the actor said the claims made against him were “not accurate” and said he completely supports “people coming out and being able to have a voice because they didn’t have a voice for so long.”
