These performances earned him praise from critics who had initially doubted his acting depth. By the early 2020s, Jamshidi had become a respected figure in Iranian cinema, capable of carrying both commercial hits and art-house projects. His role in World War III (2022), directed by Houman Seyyedi, was a turning point — a dark, introspective performance that showcased his dramatic range and emotional gravity. The film was screened at international festivals, marking his entry into a global audience.
Jamshidi has developed enduring partnerships with several Iranian filmmakers and actors. He frequently appears alongside stars like Sam Derakhshani, Hooman Seyyedi, and Reza Attaran, forming what critics call a new “comedy ensemble” generation in Iranian cinema. He has also collaborated with directors known for balancing humor and social critique — including Saman Moghadam, Manouchehr Hadi, and Ebrahim Ebrahimian — who often craft roles specifically suited to Jamshidi’s blend of realism and wit.
