America Ferrera, Katy Perry and Scarlett Johansson to join women's march
Hollywood stars are to turn out in force for a women's march on Washington set to follow Donald Trump's inauguration as US president.
Actress America Ferrera will chair the march's "artist table", organisers said, while other well-known names set to participate include Katy Perry, Amy Schumer, Scarlett Johansson, Cher and Julianne Moore.
In a statement, Ferrera said: "Since the election, so many fear that their voices will go unheard.
"As artists, women, and most importantly dedicated Americans, it is critical that we stand together in solidarity for the protection, dignity and rights of our communities."
Johansson, who criticised the incoming administration for "attacking" reproductive rights, said she would participate to "make my voice heard and stand up for what I believe in".
Organisers expect more than 100,000 people to turn out for the march on January 21, one day after Mr Trump's inauguration.
Chelsea Handler will lead a sister march in Park City, Utah - one of more than 150 solidarity marches planned around the country and the world on the same day.
Others who plan to participate in the Washington march include: Debra Messing, Uzo Aduba, Patricia Arquette, Danielle Brooks, Diane Guerrero, Padma Lakshmi, Olivia Wilde, Constance Wu and Zendaya.
