Production
Development
In May 2016, Lee Je-in and Jeon Chan-ho signed a contract with Seoul Broadcasting System's Studio S to write a 20-episode television series which could not be broadcast on any other channel. Studio S provided them with a workplace, but the production was eventually cancelled due to the difficulties with finding directors and actors. In December 2018, the duo were put in charge of writing the remaining 36 episodes of Fates & Furies when the previous screenwriter left after 4 episodes. However, Studio S did not pay the ₩60 million writing fees due within 15 days after the conclusion of the series. The duo terminated their contract with Studio S afterward and turned to JTBC for the broadcast of Sisyphus: The Myth. Studio S filed a lawsuit which they lost in November 2020.
Casting
In late September 2019, JTBC confirmed that Cho Seung-woo and Park Shin-hye would star in Sisyphus: The Myth with Jin Hyuk directing.
