Mitch Hurwitz and a few cast members appeared at a Netflix event today, and Hurwitz expanded a little bit
on plans for the new season.
[...] Netflix chief Ted Sarandos confirmed that all 10 episodes of Arrested's long-awaited fourth season will premiere together on a single day sometime next year. Hurwitz also confirmed that production is set to begin this summer [...]
Originally, Hurwitz's plan had been to make the revival like an anthology, with each episode telling a somewhat self-contained story about a specific character. "That is now kind of evolving into becoming more like the old show again [...]"
"There's going to be some mystery sprinkled throughout this [but] instead of watching one a week and try to get ahead of it, the hope is [fans] will watch them all together and then go back and look for clues and connections," Hurwitz explained. "We'd also like to use the technology to provide additional material, where you might be able to access another part of the story."
