The new voices of 'Rick and Morty' have been revealed! Adult Swim just dropped the trailer for season seven of the Emmy-winning sci-fi comedy, and it features the voice actors who are replacing co-creator Justin Roiland after he was dismissed from the show due to misconduct allegations. As fans of 'Rick and Morty' know, Roiland previously voiced both of the show's main characters. But he's been replaced with two voice actors, one for Rick and another for Morty.
