Throughout its six seasons, “Community” has boasted a variety of guest appearances and regular appearances from high-profile and established cast members. A good number of them have also appeared in “Rick and Morty” over the years.
Perhaps the most obvious is Keith David, who appeared in the final season of “Community” as Elroy Patashnik, a failed inventor. The actor continues to appear occasionally as President Curtis in “Rick and Morty.”
John Oliver, who most people probably know as the host of HBO’s “Last Week Tonight,” appeared on “Community” as Greendale psychology professor Ian Duncan. In 2013, Oliver also voiced an amoeba named Dr. Xenon Bloom in “Rick and Morty” Season 1, Episode 3 (“Anatomy Park”).
Nathan Fillion, who appeared as Greendale’s guardian in “Community” also appeared in “Rick and Morty” as a galactic secret agent who wants access to Rick’s formula for interdimensional travel in season 3, episode 1 (“The Rickshank Rickdemption”).
Since “Rick and Morty” is still airing, it remains to be seen if any other cast members from “Community” will appear in the sci-fi animated series. To date, “Community” series regulars Danny Pudi, Donald Glover, Yvette Nicole Brown and Chevy Chase have yet to reprise the voice roles on the show.
