Both projects were produced by Mojtaba Amini, who then was selected as president of the Fair Film Festival.

The first season of "Gando" comprising 30 episodes was aired on IRIB Channel 3 in 2019.
It sparked some criticism from Iran's Foreign Ministry, which was portrayed as an uninformed, neutral and Westernophile organization in the series.
