How did the new Amir replace a loser?

Asghar Farhadi says that he initially intended to use an amateur actor for the lead role in “Hero”, but the subtleties of this role led him to choose a professional actor.
Theater News Base: Asghar Farhadi on the sidelines of Amazon Studio’s panel discussion as part of the International Film Awards special event in the Deadline Awards, explained that he did not always want to use a professional actor for the lead role in “Hero” and in the casting stage. He thought that all the characters should be played by those who are acting for the first time in order to bring the work closer to a documentary.
However, when Farhadi considers the requirements of the main role of his film, which is a simple character in a complex situation, he realizes that he needs a professional actor for this role, and after watching the movie “Cold Sweat” starring Amir Jadidi Eventually, he chooses him to play Rahim in his film.
Farhadi explains: “It is more difficult to create an unknown character than a character who shows what is going on in his mind. “We worked for months on the physique and smile of Rahim’s character, and we had a lot of time to work on the games because of the corona epidemic and quarantine.”
The director of “Ghahraman”, who is the representative of Iranian cinema in the category of the best international film at the 2022 Oscars, also commented on the subject of this film: “When I started writing the script, I never thought social media would be part of the story. Gradually entered the film. “I do not want to be a social media critic and I just wanted to be a part of the film.”
