Motamed-Aria caused an uproar among Iranian religious conservatives when she attended the 2010 Cannes festival without a head scarf.
The day after the attack, Kashan’s Friday prayer leader called for a “day of mourning” in protest against Motamed-Aria’s appearance.

The many limitations on women in Iran’s film industry have been well documented in the past 37 years since the Islamic Revolution. But the attack in Kashan has even shocked government and industry officials not known for their defense of female artists.

Day of Mourning
The following day Ayatollah Abdolnabi Namazi, Kashan’s Friday prayer leader, declared Motamed-Aria’s presence in the city “a great calamity” and called for a day of mourning on Friday, February 5. 
“Everyone should know Kashan’s place in the history of Shiism,” said Namazi. “Kashan has no tolerance for immoral gatherings.”
Namazi rejected the legitimacy of the event’s permit issued by the Ministry of Culture and Islamic Guidance and even called on the Judiciary to arrest and punish the officials who stood their ground and prevented protesters from stopping the event.
He also accused Motamed-Aria of having “a history of removing her hijab,” adding that “Her clothes appeared so [inappropriate] that they tried to hide her in the street so no one would see her in that condition.”

In September 2009, Motamed-Aria was prevented from leaving the country to attend the Oscars in the US to discuss the state of Iranian cinema. Her ban was seen as punishment for her support of Iran’s Green Movement, which grew out of peaceful protests against Mahmoud Ahmadinejad’s disputed 2009 presidential election.
In 2010, Motamed-Area attended the Cannes Film Festival without wearing a hijab over her head. The government reacted by banning her from working, which lasted until President Hassan Rouhani’s election in 2013...

In previous years, several female actors have been reprimanded for the way they have dressed at events abroad. Two officials called for actress Leila Hatami’s prosecution because she shook hands with the 84-year-old head of the Cannes Film Festival in 2014. 

A year earlier the Oscar winning director Asghar Farhadi was publicly scolded by hardliners for shaking Madonna’s hand when receiving an award at the Golden Globes.
Golshifteh Farahani, who moved to France in 2009 to pursue her acting career, told the BBC in an interview that before leaving Iran, she was told by Intelligence Ministry interrogators that she was no longer wanted in the country. 

“They told me, ‘You are our problem. You should not be in this country,’” she said.
