Modest Reception is about that It is clear from this film's explosive opening sequence that there is more to Leila and Kaveh than meets the eye. Armed with sacks of banknotes, the pair are on a mission to donate millions to the needy of rural Iran - whether the targets of their philanthropy want the money or not. The couple's ambiguous relationship shrouds them in mystery, and as we follow them on their quest, it becomes clear that Kaveh's increasingly sadistic nature threatens to overwhelm their good deeds. There are subtle nods to Tarantino’s dark humor in this gripping drama, which questions the very nature of charity itself.

The Fourth Wall is about that Set informally, the audience stands close to the actors, as they perform without elaborate costume or artificial set to distract from the action. Narrated by two solemn guides, director Amir Reza Kouhestani, takes us on a journey through space and over geographical borders. It is a self-reflective piece that considers different versions of similar things. One culture is contrasted with another. A performance space is compared to an exhibition space. With skilled acting from Rambod Javan and Negar Javaherian, 'The Fourth Wall' is a bold and thought-provoking piece of theater. In this film Amir Reza Kouhestani (امیررضا کوهستانی) collaborates with Negar Javaherian (نگار جواهریان‎), Rambod Javan (رامبد جوان)

Ivanov is about that In this modern retelling of Anton Chekhov's 'Ivanov,' the eponymous character's loss of appetite for life is portrayed through his attachment to his mp3 player and headphones. However, while making such innovative changes, this adaptation maintains all the drama and social insight of the original tale of love, debt, and despondency. As Ivanov attempts to flee from his ill wife and falls in love with the younger Sasha, Chekhov's classic is brought to life with a thoroughly entertaining and thought-provoking flair.
