The director, Timo Tjahjanto, through his Twitter account, hinted this as the first movie in a planned trilogy. He also hinted that the next movie will focus on the operator (played by Julie Estelle) and the remaining member of the Six Seas.
This movie is the first Indonesian film produced by Netflix. Yet in Indonesia, one of the local largest internet & network provider (Telkomsel, who has 46% of the Indonesian wireless service market share) banned and blocked Netflix from their service.
The third movie to feature Julie Estelle, Iko Uwais and Zack Lee, following The Raid 2 (2014) and Headshot (2016).
Even though it's listed as TV-MA on Netflix, this is the first time an action movie fully embraces an NC-17 rating purely for graphic violence and gore and pushes it to the very MAX, another time being when headshot fully embraced it purely for the same reason
Yayan Ruhian, Arifin Putra, Cecep Arif Rahman, and Very Tri Yulisman were originally part of the cast, but ended up finding other projects before Timo Tjahjanto could get the funding.
