As to why they announce the cast now, he stated, "It's not easy when you're working with people from different cultures! But it's precisely that process that can yield something special! For now, we're able to announce the main cast! Rather, we need to hurry and announce it or else it'll be leaked, apparently! Hilarious, lol."
The upcoming first season of the series will have a total of 10 episodes, with the first episode of the series confirmed to be titled "Romance Dawn", the manga's first arc that introduced us to Monkey D. Luffy and his first crewmate, the pirate hunter Roronoa Zoro. As previously reported, the series will be produced by Marty Adelstein and Becky Clements of Tomorrow Studios (Cowboy Bebop, Snowpiercer), with Adelstein stating that the series will start with the very first arc of the series, the East Blue Arc. He also stated that the series promises to create "a true One Piece" after he discussed the project with series creator Eiichiro Oda personally. Oda previously stated that he will "never betray the fans who have supported me for 20 years."
Joining the show's staff are Steven Maeda (Lost, The X-Files) as its writer, showrunner, and executive producer, and Matt Owens (Agents of S.H.I.E.L.D., Luke Cage) as its writer/executive producer. One Piece is a co-production between Netflix and Tomorrow Studios, with Netflix handling physical production.
