Mahmoud Mansoori (محمود منصوری) has been a Actor in some movies:

The Horn is about that On a wintry day, a young man arrives on a bus to find it packed with frustrated passengers and no driver. There are tight close ups of the impatient passengers, who are all getting to their wits' end due to the freezing cold and lateness of the driver. ...The passengers vocalise their discontent and implore the man to honk the bus' horn, saying they will have his back. This leads to the driver, an old and cantankerous man, arriving, going on a tirade and demanding to know the identity of the person who honked the horn. This quirky short explores themes of peer pressure and group mentality with its simple and unique concept. In this film Mahmoud Mansoori (محمود منصوری) collaborates with Rouhollah Masroor (روح الله مسرور), Ehsan Eskandari (احسان اسکندری), Mohsen Roustai (محسن روستایی), Rouhollah Rezaei (روح الله رضایی)
