The series is set to debut Nov. 4 on Disney+ internationally and Hulu in the U.S.

The production is being touted as one of Disney+'s biggest investments in a Korean series since the service launched in the country in 2021. It's also part of a broader push to boost originals output three-fold across the company's international markets over the coming three years.

Disney+ is also looking to strike more co-production deals with Korean broadcasters, hoping to improve both the quality and reach of shows for both partners.

 I'm hoping that we can sort of lift all boats a little bit with some more partnerships, and we really seek those out, and have an entire team devoted to it,  Wax said.

One example is the hit romance Perfect Crown, made with Korean broadcaster MBC. Wax pointed to the series as evidence of Korean content's vastly expanded appeal beyond the violent thrillers and dark dramas that helped draw the attention of international viewers in the earliest days of the Korean wave.

 The Korean market is mature enough now, clearly, that I think you really have to judge it on all the same points that you would judge U.S. content in that it can be slick, it can be well produced, but that's not enough,  Wax said.  It has to have a good character journey. 

The streamer also has more anime and Japanese live-action content in its sights.

 We want to do more,  Wax said, with a new series based on Death Stranding, the game from Metal Gear creator Hideo Kojima, planned for 2027.  But we need to walk before we run in Japan,  he added, noting that the Japanese production sector tends to move at a very deliberate pace.

 Korean content has already shown its ability to break out, and so we're riding that wave a little more readily, but with Japanese content, we really want to make sure it works locally first,  he added.
