 * Notes

Malhun Hatun
The series was initially named Diriliş: Osman. Aslıhan Karalar, the actress who played Burçin Hatun, was imagined to play the role of Malhun Hatun, who did not appear in the first season. Aslıhan Karalar was the first actress confirmed to join the series. However, in series, Osman's first partner is Bala hatun who was played by Turkish actress Özge Törer. This was only verified after the series' first episode. Before Season 2, Özge Yağız and Yağmur Öztürk were expected to play the role of Malhun Hatun due to the fact that they both shared videos of them taking fencing lessons. This thought was dropped after Özge Yağız took part in the TV series Sol Yanım and Yağmur Öztürk took part in the TV series Acemi Anneler. Yağmur Öztürk was still, however, rumoured to play the role at some point. The 43rd episode trailer then revealed that Funda Güray was likely to play this role, however, it turned out that she would portray Aksu Hatun. It was later confirmed that Yıldız Çağrı Atiksoy would play the part.
