Sam Register Departs Warner Bros. Animation After 18-Year Run
Longtime Warner Bros. Animation chief Sam Register is leaving after his contract expired, with Warner Bros. Discovery confirming a mutual decision not to renew. A leadership transition is underway: Matt Matzkin will continue to run business operations while a replacement search unfolds, and creative department heads will lead their respective teams. Register, who joined in 2007 and expanded oversight to Cartoon Network Studios in 2020, oversaw shows such as Looney Tunes Cartoons, the Animaniacs revival, Harley Quinn, Young Justice, and more, and expressed gratitude for the ride and excitement for his next chapter.
