Rick & Morty started airing on Adult Swim back in 2013, yet a decade down the line, the show has only aired five seasons. However, the last two seasons have managed to air consecutively with the upcoming sixth season only a couple weeks away from premiering as well (September 4th). Part of why the production has been more efficient stems from the fact that back in 2018 (after the third season aired), Adult Swim made a deal with the show's co-creators Dan Harmon and Justin Roiland to produce 70 episodes.
With each season having 10 episodes (minus the first season which had 11), that guarantees the show through 10 seasons. However, while speaking in a roundtable interview with Screen Rant for the show's next season, Harmon chimed in that he expects the show to go on far past their current deal:
"Well, in my opinion, yeah, I very much expect the show to go beyond that [70-episode] order. I don’t think that’s jinxing it, I mean, it just seems like, 'Okay, we’ve got a certain amount of momentum here.' The 70-episode order, to me, was like, 'Well, how much can we commit to?' It was a two-way street between us and the network saying we’re going to take this very seriously, right? We’re not going to go develop a bunch of stuff unless we hire like a Scott Marder to run the shop. But in any case, it’s a commitment to professionalism and stuff, and it was an important one. It’s like, 'Oh, we got tenure, we’re told that we have a job tomorrow no matter what we do.' The result of that a couple of steps later is now Scott has got the show on such a schedule that, for the first time in the show’s life, we’re looking at doing a season every year. It worked great, getting that order was exactly what we needed to grow up."
The first five seasons are currently available on Hulu and HBO Max with the episodes of the new season set to air first on Adult Swim before landing on HBO Max the next day. Stay tuned!
