Back to the Future (also known as Back to the Future: The Animated Series) is an animated science-fiction comedy adventure television series for television based on the live-action Back to the Future film trilogy. The show lasted two seasons, each featuring 13 episodes, and ran on CBS from September 14, 1991 to December 26, 1992 with reruns until August 14, 1993. The network chose not to renew the show for a third season (citing low ratings). It was later rerun on Fox, as a part of the FoxBox block, from March 22 to August 30, 2003. Although the series takes place after the films, creator Bob Gale has stated that the animated series and the comic books take place in their own 'what if' and alternate timelines. This show marked the debut television appearance of Bill Nye on a nationally broadcast show. Premise Following the conclusion of Back to the Future Part III, in 1991, Dr. Emmett Brown moved into a farm in Hill Valley with his wife Clara, their sons Jules and Verne, and the family dog, Einstein. As with the films, time travel was achieved through the use of a modified DeLorean, which had apparently been rebuilt after it was destroyed at the end of the trilogy. The DeLorean now has voice-activated "time circuits" and can also travel instantaneously to different locations in space and time, in addition to folding into a suitcase. The characters also travel through time using the steam engine time machine Doc invented at the end of the third film. Although Marty McFly is a main character and Jennifer Parker makes occasional appearances, the show focused primarily on the Brown family, whereas the films focused on the McFly family. The film's villain, Biff Tannen, also appeared frequently. In addition, relatives of the McFly, Brown, and Tannen families were plentiful in the past or future parallel time zones visited. Unlike the films, which took place entirely in Hill Valley and the surrounding area, the series frequently took the characters to exotic locations. At the end of every episode, Doc Brown would appear to do an experiment, often related to the episode's plot. The first season also included post-credits segments with Biff Tannen telling a joke related to the episode, alluding to Thomas F. Wilson's career as a stand-up comedian.
