10 Most Surprising Rick And Morty Celebrity Cameos
8. Nathan Fillion
Nathan Fillion is something of a cult actor, so his casting in the season three premiere of Rick and Morty made complete sense.
His role in the episode The Rickshank Rickdemption as one of the Galactic Federation interrogators, Cornvelious Daniel, is a masterclass for any future guest stars, as he balances comedy and drama beautifully.
As the alien responsible for interrogating Rick in order to get the secret to interdimensional travel, Fillion manages to add some gravitas to the show while also playing an alien who shows arousal when his 'flappy doodles' twitch.
He is also the first and only celebrity who has had the chance to impersonate Rick, when Rick's brain is transferred into his alien body, absolutely nailing the gruff voice and the excessive burping.
