Rick Sanchez of the American animated series Rick and Morty (voiced by Justin Roiland) began as a parody of Doc Brown; in September 2021, Christopher Lloyd portrayed Sanchez himself in a series of promotional interstitials for the series' two-part fifth season finale, alongside Jaeden Martell as Morty Smith (also voiced by Roiland in the series), a character inspired by Marty McFly. Addressing Roiland's and his own portrayals of Rick compared to Doc Brown, Christopher Lloyd stated "that he felt like Doc and Rick were like two brothers that took different paths".
