A Hero (Persian: قهرمان, romanized: Qahremaan) is a 2021 drama film written, co-produced and directed by Asghar Farhadi, starring Amir Jadidi, Mohsen Tanabandeh and Sahar Goldoost.

Rahim Soltani is temporarily released from prison for a two-day period in order to settle an unpaid debt of 150,000 tomans to his brother-in-law, Bahram.

Bahram is immediately suspicious of Rahim's story, believing he is trying to restore his image and leave prison to stop the impending second marriage of his ex-wife.

In the course, Farhadi assigned his students to research and film a documentary about people who had found and returned valuable objects to their original owners.

Masihzadeh then went to a local newspaper and the TV station that aired the news, obtained permission to film in prison, and met Shokri.

[14] Under the title All Winners, All Losers, the film screened at the Shiraz Arts Festival in 2018,[10] where it won the Special Jury Prize.

[11] A lawyer for Memento Films, the French producer and distributor of A Hero, later pointed out that the document had no legal value as "ideas and concepts are not protected by copyright".

[14] In September 2021, Masihzadeh's lawyer sent Farhadi a message stating that her intellectual property rights had been violated and requesting "dialogue and negotiation".

[12] A month later, a meeting was held at the House of Cinema [fa], where Farhadi's lawyer told Masihzadeh that she had committed the crime of defamation and that a complaint would be filed against her if she did not delete her Instagram posts.

[12] In early November 2021, Farhadi filed a criminal complaint with the Tehran Culture and Media Court [fa], accusing Masihzadeh of defamation and spreading misinformation.

On November 30, 2021, Masihzadeh filed a counterclaim, accusing Farhadi of plagiarism, intellectual property theft, and "illegitimate gains by fraud or abuse of privilege".

In January 2022, Farhadi filed another complaint accusing Masihzadeh of defamation and misinformation, in regard to her claim that she was coerced to sign a statement.

[12] On 13 March 2024, a court issued a verdict acquitting Farhadi of the plagiarism charges, based on the opinion of a panel consisting of three University of Tehran professors specialising in copyright law and four official art experts, which stated that the events depicted in the documentary had been widely reported in media and belonged to the public domain.

Shokri filed a complaint against Farhadi for defamation and revelation of personal information, among other charges, stating that he had granted Masihzadeh an exclusive permission to depict his story.

The website's consensus reads: "A Hero finds writer-director Asghar Farhadi once again grappling with weighty themes – with the audience emerging as the winner.
