Paramount is doubling down on Sonic.

A third Sonic the Hedgehog movie is being developed by the studio, while a live-action series centering on the Idris Elba-voiced Knuckles is set for streaming service Paramount+.

The first Sonic film came out in 2020 and earned $320 million at the worldwide box office, while the sequel is set for release on April 8 and will introduce Elba’s Kunckles. For the sequel, Ben Schwartz returns as the voice of the iconic Sega videogame character, along with a supporting cast that includes Jim Carrey and James Marsden. Director Jeff Fowler also returns for the follow-up, along with writers Pat Casey and Josh Miller. It is currently unclear if the filmmaking team will return for the third film, which is still in early development.

Sega and Paramount+ are developing the live-action Sonic series, centering on Knuckles, which is set to launch in 2023. A creative team has yet to be announced.

The live-action “Knuckles” series at Paramount+ has added five new cast members.

Cary Elwes (“The Princess Bride,” “Robin Hood: Men in Tights”), Stockard Channing (“Grease,” “The West Wing”), Christopher Lloyd (“Back to the Future,” “The Addams Family”), Paul Scheer (“Black Monday,” “Veep”), and Rob Huebel (“Children’s Hospital,” “Bob’s Burgers”) have all joined the series. Details on their characters are being kept under wraps.

As previously announced, Idris Elba will once again voice the character Knuckles as he did in the film “Sonic the Hedgehog 2.” Other cast members include Adam Pally, reprising the role of Wade Whipple, as well as Edi Patterson, Julian Barratt, Scott Mescudi, and Ellie Taylor. Guest stars include Rory McCann and Tika Sumpter, with the latter reprising her role as Maddie.

The show was originally announced in February 2022. It is set in the time between “Sonic the Hedgehog 2” and the third film in the franchise, which is slated to debut in theaters on December 20, 2024. In the series, Knuckles “agrees to train Wade as his protégé and teach him the ways of the Echidna warrior,” per the official logline.

John Whittington, who worked on the screenplay for “Sonic the Hedgehog 2,” wrote the pilot for “Knuckles” and serves as head writer and executive producer on the series. Brian Schacter and James Madejski are also writers.

Jeff Fowler, who directed both “Sonic the Hedgehog” films, will direct the pilot episode and executive produce the series. Neal H. Moritz and Toby Ascher of Original Film and Toru Nakahara — all members of the films’ creative team — serve as executive producers, as does Elba. Ged Wright, Brandon Trost, Jorma Taccone, and Carol Banker are also directing episodes. Paramount Pictures and Sega of America produce.

The new live-action series will follow Knuckles (Idris Elba) on a hilarious and action-packed journey of self-discovery as he agrees to train Wade (Adam Pally) as his protégé and teach him the ways of the Echidna warrior. The series takes place between the films SONIC THE HEDGEHOG 2 and SONIC THE HEDGEHOG 3.

Stream Knuckles April 26, exclusively on Paramount+ in the U.S. and Canada.

The series will stream on April 27 in all additional Paramount+ territories, and in Japan later in the year.
