Adult Swim’s animated science fiction series “Rick and Morty” recently released its mini-episode, giving their long-time supporters a quick look at its third installment. In addition, rumors are spreading that “Fast 8” star, Vin Diesel, will be joining the hit show to voice one of its characters.

International Business Times reports that during an interview with the New York magazine, Creator Justin Roiland, who also provides the voices of Rick and Morty, said that he had improvised some of the scenes in the short, which is titled “Summer’s Future.”

The four-minute video starts with Spencer Grammer, Dan Harmon, Justin Roiland and Ryan Ridley sitting in a circle while Harmon presents the principle of the short episode. As Rick works in his garage, Roiland and Grammer talk about Summer who is asking Rick’s assistance for her college application.

Instead of helping Summer, Rick puts his focus on his experiment in which he injects 120 cc of feces into Morty’s knees. Rick's research turns out to be incredible, thus, Summer was awarded a full scholarship by Harvard's Dean of Admissions. Ironically, the experiment testing has killed Morty.

Despite the showrunners’ keeping mum about other details that might spoil the upcoming season, Don Harmon is keen in having one of their dream guests for a voice over. “I just want to meet Vin Diesel. I know he plays D&D so I just want to have a conversation with him about doing it.” The “Fast and Furious 8” star and producer Vin Diesel had contributed exemplary voice over jobs in “The Iron Giant” and “Guardians of the Galaxy.” 

During the San Diego Comic-Con 2016, Harmon admitted that the production of the third season is harder and more difficult to make compared to the previous season.

Cheers to a happy holiday as Rick & Morty Season 3 is slated to air by year-end.
