Final Space Season 4 - What We Know So Far

Since its debut on TBS in 2018, Olan Rogers and David Sacks' animated series "Final Space" has provided plenty of laughs along with tension throughout its completed two seasons, with the second switching platforms to Cartoon Network's night-shift channel, Adult Swim. With Season 3 over and done, fans are already looking forward to what might be next for the series, including the fates of our protagonists Gary Goodspeed and Mooncake (both voiced by Rogers himself) and the mystery of the titular Final Space.

The series has acquired a passionate and dedicated fanbase, in large part thanks to its excellent animation and blend of comedy with more serious moments, as well as a truly stellar voice cast including the talents of David Tennant, Tom Kenny, Conan O'Brien, Ron Perlman, and more.

Although there's still a lot we don't know about the future of the series, here is everything we do know about Season 4 of "Final Space," including any information or educated guesses we have about its release date, cast, and plot.

Updated July 29, 2021: This article has been updated with news of the series cancelation after Season 3.

Final Space has apparently been canceled

To the dismay and despair of fans everywhere, "Final Space" creator Olan Rogers officially confirmed that his show had been canceled, and that Season 3 would be the last (via Collider). That's devastating news — there really isn't any other way to slice it — but given the infinite possibilities for revival in the age of streaming, let's imagine a world in which Season 4 might happen. 

After the first season's finale finished airing, we immediately got confirmation of a second season the same day, and we only had to wait a week after the show's second season finale to get confirmation for a third season. If someone does step in to revive "Final Space" for a fourth season, we'll probably have to wait about a year before we see any new episodes produced pursuant to that decision.

Who might be in the cast for Season 4 of Final Space?

Without an official confirmation, we certainly don't have an official cast list, but we can again make some educated guesses based on what information we have.

Due to the series messing with multiple timelines, not even death is a final confirmation that we won't see any particular character again, so no matter what happens in Season 3, be prepared for anything and anyone to return for Season 4.

We can safely assume that series protagonist Gary Goodspeed would return with Olan Rogers in the lead role, as well as voicing a number of supporting characters. Other mainstays we've heard voice multiple characters include Tom Kenny (HUE, SAMES), Fred Armisen (KVN, Eduardo), Tika Sumpter (Quinn Ergon, Nightfall) and Steven Yeun (Little Cato, Mr. Graven) voicing a collective total of 48 characters, although IMDb's "additional voices" suggest the actual number may be much higher when including incidental characters.

As far as other cast members we hope will return, there's Ashly Burch in the role of Ash Graven, Ron Funches as Fox, Claudia Black as Sheryl Goodspeed, Vanessa Marshall as Invictus, and, of course, David Tennant as the villainous Lord Commander.

What can we expect for Final Space Season 4's plot?

Since the show's been canceled, it's difficult to fully predict what we might have seen in Season 4.

Season 3 really leaned into the darker themes of the show, with the recurring tagline and theme being "survival" as its characters find themselves trapped within Final Space itself. Given that most characters survived the last season, we might expect the next one to play off these themes with more empowered characters, using the knowledge they now have of Final Space and the universe in order to avenge any fallen heroes and go after Invictus. 

The Season 3 finale left plenty of room for this story to continue in a number of potential directions. If another network or streamer does save the series, the creative team will have to pick up where they left off, and contend with the ramifications of Season 3. If that doesn't happen? Well, we're all stuck with a largely unsatisfying ending.
