"In solidarity with the peaceful fight she leads for freedom and women's rights", the Cannes Film Festival sent her "all its support" on social networks on Monday.
Taraneh Alidoosti is the most famous personality arrested in connection with the protest movement agitating Iran for three months.
Celebrities and human rights defenders have been calling since this weekend for Iran to release the actress and activist.
The Office of the United Nations High Commissioner for Human Rights told AFP "deeply concerned" by this arrest, stressing that "all those arrested for having demonstrated peacefully must be released immediately".
The British pop group Pet Shop Boys, denouncing a "fascist government" in Iran, posted a photo of the actress and several links to articles on her arrest on their social networks.
"The brave actress from Iran has been arrested," wrote her colleague Golshifteh Farahani, who began her career in Iran before fleeing, on Instagram.
Taraneh Alidoosti "is one of Iran's most talented and recognized actresses," wrote Cameron Bailey, director of the Toronto film festival in Canada.
"I hope she will be released soon to continue representing the strength of Iranian cinema."
Taraneh Alidoosti, 38, is known abroad for having starred in award-winning films by director Asghar Farhadi, including "The Client", Oscar for best foreign language film in 2017. She also starred in Saeed Roustayi's film "Leila and her brothers", presented this year at the Cannes Film Festival.
