During his year off from Community, Dan Harmon co-created a Back to the Future-esque animated series called Rick and Morty. Justin Roiland (Channel 101) co-created the show with Harmon, and the voice cast features Roiland, Chris Parnell, Phil Hendrie, Alison Brie, Brandon Johnson, and other people too. Rick and Morty is set to premiere this December on Adult Swim, and here’s a brand new trailer for it.
