Arcane

Arcane is an upcoming animated streaming television "event series" set in the League of Legends universe. The series was announced at the League of Legends 10th Anniversary celebrations. It will be developed and produced by Riot Games, with animation services by Fortiche Productions. Originally set for a 2020 release, the show is rescheduled for a release in 2021 due to the COVID-19 pandemic. It is scheduled for a simultaneous November 6, 2021 release on Netflix and China's Tencent Video website, with the series broken into 3 episode "acts" released over 3 weeks.

Set in the past, it retells the origin stories of several characters from Piltover and Zaun. Like the game which it is based on, Arcane is aimed at a "14+" audience and will deal with some more adult subject matter.

In September 2021, it was announced that Hailee Steinfeld, Ella Purnell, Kevin Alejandro, Katie Leung, Jason Spisak, Toks Olagundoye, JB Blanc and Harry Lloyd had joined the voice cast.
