Rick and Morty fans anxious over radio silence regarding the Adult Swim series' uncertain return may have just received a bit of good news. Series co-creator Dan Harmon has provided a brief update on the status of contract negotiations for a proposed fourth season.

"I’m optimistic right now, at the moment," Harmon said in an interview with Den of Geek at Tribeca Film Festival. "Negotiations are tough. It’s an unprecedented situation, and everybody’s being real cool and wants to make an agreement happen so that we can get started. That’s about all I can say.”

Harmon's level-headed statement is a sharp contrast to his tweets last month, admitting that Cartoon Network had not renewed the series for a fourth season, as well as comments from writer Ryan Ridley in January that a writers room for a new season had yet to be established and that the co-creators and Cartoon Network needed to "get their s— together.”

Fans of the popular animated series are familiar with long waits, as there was a 22-month delay between Season 2 and Season 3, not counting a surprise special episode on April Fools' Day last year.

Rick and Morty, created by Justin Roiland and Dan Harmon, first premiered on Cartoon Network’s Adult Swim programming block back in 2013 and has gone on to air three seasons since. Of course, as fans will note, the third season had a long documented journey to the small screen. The show’s most recent episode, “The Rickchurian Mortydate,” aired in October of last year, concluding the third season.
