Daniel Radcliffe is entering the world of Kimmy Schmidt.

The “Harry Potter” actor will star in the upcoming “Unbreakable Kimmy Schmidt” interactive special at Netflix, set to debut in 2020.

The special will see Kimmy Schmidt (Ellie Kemper) set off on her biggest adventure yet across three states. As with Netflix’s “Black Mirror: Bandersnatch” movie and other interactive shows, viewers will be able to make choices on behalf of the show’s characters and take them down different story branches — and they’ll get different jokes.

In announcing the addition of Radcliffe, Netflix also teased the appearance of Kimmy’s kidnapper, the Rev. Dr. Richard Wayne Gary Wayne played by Jon Hamm, in the special. Cast returning for the interactive special include Kemper, Tituss Burgess, Jane Krakowski and Carol Kane.

Netflix’s order for the special came after the fourth and final season of the show dropped in January. In its announcement, Netflix quoted Tina Fey, co-creator and executive producer, as saying the interactive special “will be a great way to officially complete the series.”

Over its four-season run, “Unbreakable Kimmy Schmidt” earned 18 Primetime Emmy Award nominations, including for best comedy series, but was shut out from any wins.

The show was created and executive produced by Fey and Robert Carlock. Jeff Richmond, Sam Means, David Miner and Meredith Scardino also serve as executive producers. “Unbreakable Kimmy Schmidt” is a production of Universal Television, Little Stranger, Bevel Gears and 3 Arts Entertainment.
