Hatami played several small roles in her father's productions throughout her youth, including in the Hezar Dastan television series and the Kamalolmolk movie. Her first leading film appearance was the title role in the 1996 filmLeila., directed by Dariush Mehrjui. She received the Diploma of Honor for Best Actress from the 15thFajr Film Festival. Following this, she continued to act regularly in Iranian cinema. She has starred in dozens of films, and has often garnered critical acclaim and accolades. For her performance in The Deserted Station, she was nominated for the Fajr International Film Festival Award for Best Actress and she won the Best Actress Award at the 26th Montreal World Film Festival. She has appeared in her husband's films as a director, Portrait of a Lady Far Away and The Last Step. She also designed the sets and the costumes of The Last Step and, in addition to receiving the Karlovy Vary International Film Festival Award for Best Actress for her performance, she received a nomination for the Crystal Simorgh Fajr International Film Festival Award for Best Production Design and Costume Design for her work on the film. In 2012, she received international attention for her role in the critical acclaimed Asghar Farhadi film, A Separation, which won dozens of accolades, including the Academy Award for Best Foreign Language Film. Her performance earned critical acclaim and various awards, including the Silver Bear Award for Best Actress at the Berlin Film Festival. IndieWire praised her portrayal as one of the best female performances of the 21st century. In April 2014, she was announced as a member of the main competition jury at the 2014 Cannes Film Festival. Whilst there, she greeted Cannes President Gilles Jacob with a kiss on the cheek, which is a form of greeting in France. Iran's Deputy Culture Minister Hossein Noushabadi offered criticism of her for this:
"I hope that those who attend international arenas as Iranian women would be careful about the chastity and dignity of Iranians so that the image of the Iranian woman is not tainted before the world," he said. "If they respect Islamic norms and the national culture and beliefs of Iran, it would be a desirable thing for Iranian celebrities to go abroad, but if their presence lacks regard for social values and ethical criteria, the Iranian nation is not going to accept it."
In May 2014, after receiving significant backlash for the kiss in Iran—including calls for her to be flogged—Hatimi later apologized for her actions in a letter.
