Ayhan Tas, the actor of Sezai Usta says that the source of the brilliance the production have proved is that the camera doesn't follow the actor, the actor follows the camera.
The series was used to have 3 seasons with 20 episodes each one, totally 60 episodes, but as soon as the season 2 launched, the producers shorted the rest of the series to just 13 more episodes, so it ended at episode 35. The cast surely wasn't happy about that, but they showed respect to the decision.
Murat Cemcir, the actor of Ali Özdemir, wasn't planning to start a new series, but as soon as he read the script, he changed his mind.
The actors of Metin, Ali, Himi, Sezai, Oguzhan and more had also played in Isler Gücler.
