'Rick and Morty' Season 4 Release Date One Step Closer With First Guest Voice

Rick and Morty Season 4 doesn't yet have a release date, but it has hit a new benchmark on the way to its premiere on Adult Swim. The series is back in the sound booth, not just recording Justin Roiland as Rick and Morty, but also logging vocal performances from upcoming guest stars. Most recently: Sam Neill.

Nothing is yet known about Neill's character, just a single, cryptic post:

Neill joins a long list of awesome Rick and Morty guest voices, including Susan Sarandon, Stephen Colbert, Nathan Fielder, Werner Herzog, Alfred Molina, Christina Hendricks, Keith David, John Oliver, Keegan-Michael Key, Jordan Peele, Matt Walsh, Kurtwood Smith, Gary Cole, Nathan Fillion, Danny Trejo, Lance Reddick, Gillian Jacobs, Christian Slater, Clancy Brown, Patton Oswalt, Jemaine Clement and David Cross.

Neill may be best known as Alan Grant from Jurassic Park, but he's also been a staple of sci-fi and horror, including performances in John Carpenter's In the Mouth of Madness and Andrzej Zulawski's mind-melting Possession, in which Neill's wife (Isabelle Adjani) cheats on him with a tentacle monster. Rarer in Neill's filmography are animated, voice-acted performances, though he has made a previous guest appearance on The Simpsons and voiced an owl in Zack Snyder's Legend of the Guardians: The Owls of Ga'Hoole.

In the lead-up to Rick and Morty Season 3, co-creator Dan Harmon had an answer ready for anytime someone bugged him about the release date: "they're drawing it." That's a benchmark Season 4 hit back in September (though storyboards precede the final animation created at Bardel Entertainment in Canada).

The addition of guest voices proves that, at least for some early episodes, Rick and Morty has cleared one of its most challenging hurdles: the intensive writing process. While Rick and Morty Season 4 is still months off, this is our best indication in weeks that the series is on track and less likely to suffer the multiple delays of Season 3.
