Every ‘Rick and Morty’ Celebrity Guest Voice

Rick and Morty is so good at weaving deep mythos, making irreverent social callouts, and dropping Easter egg references all over the place that celebrity guest stars are almost an afterthought.

However, the popular animated series has already had an impressive lineup of celebrities lending their voices to characters both minor and major. The famous cameos are slipped in there with such cleverly understated grace that it’s easy to miss them.

Here is every Rick and Morty celebrity guest voice from the first three seasons. Also? Worth noting here that this list doesn’t include main cast members such as Chris Parnell and Sarah Chalke or recurring characters like Keith David as the President.

Dana Carvey

The SNL and Wayne’s World funnyman voiced Jerry Smith’s cuckolded father, Leonard, in the S1E3 episode “Anatomy Park”. 

John Oliver

The Last Week Tonight host voiced Dr. Xenon Bloom, the humanoid amoeba who was Rick’s partners in building Anatomy Park, as seen in the “Anatomy Park” episode (S1E3).

David Cross

The Arrested Development and Kimmy Schmidt comedian voiced Prince Nebulon, leader of the Zigerion race that attempts to scam Rick by placing him in multiple world simulations in “M. Night-Shaym-Aliens!” (S1E4). 

Alfred Molina

The Spider-Man 2 actor followed his Gravity Falls guest spot by voicing The Devil in the Stephen King-inspired “Something Ricked This Way Comes” (S1E9). 

Key & Peele

Key & Peele stars Keegan-Michael Key and Jordan Peele appear in the Season Two premiere “A Rickle in Time”. Key has the bigger role, voicing a Fourth-Dimensional Being who tries to fix Rick’s botch-job with the time stream. Peele appears in the episode’s post-credits scene as a second Four-Dimensional Being, who helps his buddy kick Albert Einstein’s ass when they mistake the famous physicist for Rick. 

Jemaine Clement

The Flight of the Conchords and Legion star voices a gaseous being with telepathic powers, who takes on the name “Fart.” During the episode “Mortynight Run” (S2E3), Morty goes on a mission to free Fart from captivity. Clement’s musical number “Goodbye Moon Man” is a classic part of the show’s mythos. 

Christina Hendricks

Mad Men‘s bombshell redhead is the primary voice of Unity, Rick’s on-and-off-again lover, a hive mind alien bent on bringing universal order through assimilation. Unity and Rick briefly rekindle their fling in “Auto Erotic Assimilation” (S2E3). 

Patton Oswalt

Funnyman Patton Oswalt plays Beta 7, another hive mind alien who secretly pines for Rick’s lover Unity in “Auto Erotic Assimilation” (S2E3), but is stranded in the friend zone.

Matt Walsh

Veep‘s downtrodden funnyman voices Sleepy Gary, Beth’s husband (and Jerry’s lover) in a memory implanted by an alien parasite in the episode “Total Rickall” (S2E4). 

Kurtwood Smith

That ’70s Show‘s curmudgeonly dad voices the equally curmudgeonly General Nathan, who betrays The President (Keith David) in order to try a nuclear strike against the Cromulons, giant alien heads that turn Earth into an intergalactic reality show in “Get Schwifty” (S2E5). 

Stephen Colbert & Alan Tudyk

The Late Show host Stephen Colbert voiced Zeep, a Rick-like scientist in the miniature world that Rick created inside his spaceship battery. Firefly and Rogue One star Alan Tudyk voiced Chris, president of the Microverse where Zeep lives. Both appeared in “The Ricks Must Be Crazy” (S2E6).

Nathan Fielder

Zeep followed in the footsteps of his creator, creating his own miniature world in the episode “The Ricks Must Be Crazy” (S2E6). Nathan For You star Nathan Fielder voices Kyle, the Rick- and Zeep-like scientist living in Zeep’s miniature world. When Kyle learns his true origin from Morty, he promptly kills himself. 

Gary Cole & Werner Herzog

Office Space star Gary Cole and eccentric German director Werner Herzog both appeared in the clip show episode “Interdimensional Cable 2: Tempting Fate” (S2E8). 

Cole voiced an alien doctor treating Jerry Smith; Herzog voiced Shrimply Pibbles, the benevolent universal civil rights leader who needed Jerry’s genitalia to save his life. 

James Callis & Tricia Helfer

Battlestar Galactica’s hot couple, James Callis and Tricia Helfer, make a clever little appearance as Pat and Donna Gueterman, parents of Summer’s high school friend Tammy. When Tammy is revealed to be a Galactic Federation agent during her wedding to Birdperson, Pat and Donna turn out to be her robot assassins. That Cylon life is too real…

Nathan Fillion

Firefly star and geek icon Nathan Fillion voiced Cornvelious Daniel, the Federation agent who goes inside Rick’s mind when he’s being held in Federation prison. The character was also a big catalyst for that McDonald’s Szechaun sauce controversy.

Joel McHale & Tony Hale

In “Rickmancing the Stone” (S3E2) Rick, Morty, and Summer visit a Mad Max-style post-apocalyptic earth. There, Summer falls for Deathstalkers leader Hemorrhage (voiced by Community’s Joel McHale), but ultimately ends up in a dead-end marriage like her parents. Veep‘s Tony Hale voices Eli, a scrawny Deathstalker who ends up being Summer and Hemorrhage’s neighbor. 

Susan Sarandon

Oscar-winner Susan Sarandon appears in the now-infamous “Pickle Rick” episode (S3E3) as therapist Dr. Wong. With her calming tones, Dr. Wong tries to help the Smith family cope with Jerry and Beth’s divorce. 

Danny Trejo

The Machete star appears in “Pickle Rick” (S3E3) as Jaguar, the insane mercenary assassin that an evil Russian gang has locked away – until he forms an alliance with Pickle Rick to avenge his dead daughter. 

Gillian Jacobs, Christian Slater, & Lance Reddick

Community star Gillian Jacobs, Mr. Robot‘s Christian Slater, and The Wire‘s Lance Reddick play Supernova, Vance Maximus, and Alan Rails, respectively, members of a cosmic superhero team in “Vindicators 3: The Return of Worldender” (S3E4). Hip-hop star Logic also appears in the episode as himself. 

Clancy Brown

The Thor: Ragnarok actor voiced Risotto Groupon, assistant manager at the intergalactic resort where Rick takes Jerry. Groupon is the one who talks Jerry into luring Rick into a deadly trap on the resort’s “Whirly Dirly” ride, in the episode “The Whirly Dirly Conspiracy” (S3E5). 

Thomas Middleditch

The Silicon Valley star (and Verizon frontman) voices Tommy Lipnip, Beth’s childhood friend that she locked away in “Froopyland,” a fantasy dimension Rick created for her. Tommy has gone quite mad by the time Rick and Beth find him in “The ABC’s of Beth” (S3E9), trapped in a dark cycle of humping and then eating his own offspring. 

Rick and Morty will be back for Season Four sometime in 2018.
