Back to the Future: The Animated Series

Back to the Future (also known as Back to the Future: The Animated Series) is an American animated science fiction comedy adventure television series for television based on the live action Back to the Future movie trilogy. The show lasted two seasons, each featuring 13 episodes, and ran on CBS from September 14, 1991, to December 26, 1992, and reran until August 14, 1993, on CBS. The network chose not to renew the show for a third season (citing low ratings). It later reran on FOX, as a part of the FoxBox block from March 22 to August 30, 2003. It was the very first production of Universal Cartoon Studios.

Although the cartoon takes place after the movies, Bob Gale has stated that the animated series and the comic books take place in their own 'what if' and alternate timelines and are not part of the main continuity. 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, Dr. Emmett L. Brown settled in 1991 in Hill Valley with his new wife Clara, their sons Jules and Verne, and the family dog, Einstein, living on the same ranch where Clara lived in 1885. As with the films, time travel was achieved through the use of a modified DeLorean, which had apparently been re-built 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 traveled through time using the steam engine time machine Doc invented at the end of the third film.

Although Marty McFly is the show's main character and Jennifer Parker making occasional appearances, the show focused primarily on the Brown family, whereas the movies focused on the McFly family. The film's villain, Biff Tannen, also appeared frequently. In addition, relatives of 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.

Characters
Mary Steenburgen (Clara Clayton Brown) and Thomas F. Wilson (Biff Tannen) voiced their characters from the films. Christopher Lloyd played Doc Brown in the live-action segments which opened and closed each episode while Dan Castellaneta provided the animated Doc Brown's voice. James Tolkan was also featured as a guest voice in one episode, however he returned only to voice a completely different character as opposed to his Principal Strickland character from the films. In addition, Bill Nye appeared as Dr. Brown's Lab Assistant during the live-action segments at the end of each episode performing scientific experiments related to the episode. Nye also serves as the show's technical advisor. These segments later led to Nye getting his own show.
 * Marty McFly (voiced by David Kaufman) – The main character of the series. Marty spends a lot of time visiting the Brown house where Doc, Clara, and their sons live. He continues to travel through time alongside Jennifer, Doc and the rest of the Brown family on many of their misadventures. Marty and Jennifer become students at Hill Valley College after graduating from Hill Valley High School.
 * Jennifer Parker (voiced by Cathy Cavadini) – Marty's girlfriend.
 * Emmett "Doc" Brown (portrayed by Christopher Lloyd in live action segments, voiced by Dan Castellaneta in the animated segments) – Marty's best friend and the inventor of the time machine, which he built out of a DeLorean sports car in 1985 and later built a locomotive time machine from 1885 to 1895. He lives with Clara and two sons Jules and Verne.
 * Einstein (voiced by Danny Mann) – The sheep dog living with Doc, Clara, Jules, and Verne. He is also Marty's friend.
 * Clara Clayton Brown (voiced by Mary Steenburgen) – Doc's wife, who, along with the rest of the family, moved to the 20th century. She and the Browns lived in a farmhouse outside Hill Valley in 1991. Clara has settled well into 20th century life, and became a teacher at Hill Valley Elementary. She occasionally joins her husband, sons, and Marty on their time travel road trips.
 * Jules Brown (voiced by Josh Keaton) – Verne's elder brother. His middle name is Erastosthenes. Unlike younger brother Verne, Jules is intelligent for his age and, similarly to his father, uses long words in his everyday vocabulary. He calls Marty McFly "Martin". Jules is top of the class in his school; however, he is not very popular and has but a few friends. He has a crush on his classmate Franny Philips and enjoys baseball and inventing.
 * Verne Brown (voiced by Troy Davidson) – Jules' younger brother. He is a cheeky young man; however, he hates losing and doing chores. He likes video games and watching television. He is almost always seen wearing a raccoon skin cap. Unlike his older brother Jules, Verne is quite popular at school and has many friends, including Marty McFly. He acts his age, unlike Jules. Verne often uses his favorite insult, "skunkhead", primarily toward his older brother. Verne also developed a rivalry with Biff Tannen's son, Biff Jr.
 * Biff Tannen (voiced by Thomas F. Wilson) – Biff is the great-grandson of Buford "Mad Dog" Tannen and is the present day villain of the series, although most episodes feature his numerous ancestors or descendants instead (Marty once rhetorically questioned if there was a "Biff" in every time period and place they visited). In the series, Biff also has a son, Biff Jr. (voiced by Benji Gregory).
