Cartoon Network has cancelled Clarence after three seasons. Voice actor Spencer Rothbell confirms that the animated comedy will not move forward into Season 4. Rothbell says Clarence Season 3 episodes will continue airing through 2018, concluding with a “proper” series ending:
I just wanted to address some questions about Clarence. Sadly the third season will be the last; we were not renewed past Season 3. Having said that, there are still a LOT of new episodes coming – Clarence will be premiering through 2018! Season 3 has some really cool episodes in it, including some of my favorites that we’ve ever done. Expect guest stars, callbacks, returning characters, character development, experiments with format, and other fun surprises!
Some people were concerned about the series having a proper ending, but no need to worry about that either! The season ending should serve as a proper series ending as well. Of course there will always be ideas and routes I wish we could have gotten to, but this season has some really stellar episodes that expand on the universe of the show and its characters in a fun way that we haven’t really done before.
