Hill Valley's Courthouse Square in 2015.

2015 is a year in the 21st century.

On October 21, 2015, one hour before his past self would arrive with Marty McFly and Jennifer Parker, Dr. Emmett Brown went back in time to prevent a nuclear holocaust in 2045.

A new timeline was created, and most things that they originally witnessed in 2015 never existed.

Original Timeline[]

By this time in history, technology had progressed as much during the 30 years since 1985 as it had during the previous 30 years from 1955 to 1985. Electronics were in virtually everything from clothing to garbage cans to make them move, talk and/or make electronic noises.

Flying cars, once they were invented and perfected, had become so common that drivers no longer needed roads — except perhaps for short journeys. Skyways dominated the skies of central California and eventually the entire world. Cultural influences from other countries, particularly Japan, were more often seen in food and clothing.

Life was lived at a quicker pace than before, in evidence by the speed that people walked down the street, the time it took to cook dinner, and the swiftness of court trials.

Hill Valley underwent a period of gentrification, or revitalization of its downtown. With an increased concern for the environment, the Courthouse Square was landscaped with a large artificial lake (with the surrounding road having NO LANDING markings applied to dissuade drivers of flying cars from bringing their vehicles down near the lake), and businesses were brought back with the construction of an underground Courthouse Mall.

  • Timeline 1:
    • Saturday, August 8:
    • Wednesday, October 21: Marty McFly Jr. is arrested after being set up for a robbery by Griff Tannen.
    • Thursday, October 22: Marty Jr. is tried, sentenced and convicted to 15 years in the state penetentary for the robbery.
    • Wednesday, October 28: Marty's daughter Marlene attempts to break her brother out of prison. She is sentenced to 20 years in jail.
    • Dates unknown
      •  After picking up several new copies of the first issue of Action Comics in 1938, Doc returns to an unknown time in 2015 where he sells one of the comics. He then uses the discount he won to get a hover conversion by Goldie Wilson III, has his DeLorean outfitted with a Mr Fusion, and establishes a fake identity under the name Leroy Brown. Then he travels to another point in 2015 to sell another of his Action Comics at Southby's Auction House for $2.5 million dollars.
      • Doc undergoes personal rejuvenation surgery and learns as much as he can about Marty Jr.'s meeting with Griff on October 21. Doc also places Einstein in a suspended animation kennel. He places the remaining money in a bank. Eventually, Doc leaves for 1985 to pick up Marty and Jennifer.
  • Timeline 2:
  • Timeline 3:
    • Wednesday, October 21: Biff Tannen is erased from history, as his changing the past has caused him to run Hill Valley in an alternate timeline. As a result of his actions, he is not alive in 2015 in the new timeline.
      • Marty, Doc, Jennifer and Einstein travel back to 1985, not realizing that they are in a new timeline.
  • Timeline 4:
    • Friday, October 16: Statler Toyota airs a commercial featuring Jimmy Joe Statler.[1]
    • Wednesday, October 21:
      • After changing the timeline where Biff ran Hill Valley, and refusing to race Needles in 1985, the fax machine no longer prints that Marty McFly was fired from his job on this date, as Jennifer Parker witnessed the words being erased in 1985.
    • Date unknown: After being accidentally sent to 1885, where he settled to raise a family, Doc managed to create a steam time car, which he used to travel from 1893 to 2035. He then traveled in his temporal field generator Mk II from 2035 to 2015 to pick up a Mr. Fusion. After this, he took the Mr. Fusion back with him to 1985, and installed it in the second DeLorean time machine.
    • Thursday, October 22: Griff and his gang are convicted and imprisoned for crashing into the Courthouse.
  • Timeline 5:
    • Wednesday, July 15: Microsoft's failed visions of the future were actually a success, leading to an alternate timeline where Microsoft's failed digital assistants, Clippy and Microsoft Bob, were now holograms that controlled everything. This timeline was erased once Doc Brown took the senior vice president of Microsoft's Server and Tools business, Bob Muglia, back to April 4, 2007 to give a revised version of his "Visions of the Future" speech.
  • Timeline 6:
    • Wednesday, October 21:
      • One hour before his past self would arrive with Marty McFly and Jennifer Parker, Emmett Brown set up a video camera to capture video of a space time correction. He goes back in time to an unknown destination to put his plan in motion.
      • Griff and his gang crash into the Courthouse Mall, and Griff Tannen tries to unsuccessfully implicate Marty McFly Jr.  This seems to imply that Marty and Jennifer allowed their son to get involved with Griff, knowing that their past selves would come to the future to help him.

Behind the scenes[]



  1. Real-world Toyota 2015 ads show Jimmy Joe Statler with two ties and a flying car in the background, setting it in the timeline before Doc Brown erases hover technology from existence.
  2. When asking Doc why his 1931 counterpart couldn't have invented a hoverboard, Doc responds that they wouldn't be invented for another 84 years.


  • In 2015, in real life, there were no widely-produced flying cars, auto-adjusting and auto-drying jackets, power-lacing shoes, etc. Nike had produced prototype power-lacing shoes, there were prototype flying cars, such as the Transition road-able aircraft by Terrafugia, and Falyon Wearable Tech created a prototype auto-drying jacket. However, none of these will be shipping commercially until 2016. Another flying car, the Terrafugia TF-X, is planned for release in 2021.
  • In reality, in 2015, the basic concept of watching multiple channels at once, as exhibited by Marty Jr., technically existed. Televisions offered picture-in-picture functionality and various satellite TV packages offering overviews of certain groups of channels based on genre – like sports or family channels – which could be viewed all at once. Some smart TVs also supported simple voice commands which allow the viewer to control functions such as turning the TV on and off, changing channels, accessing apps, and navigating the internet.
  • Almost all of the billboards shown around Courthouse Square are holographic billboards, which were yet to be widely adopted in reality. The technology required to produce such displays was still in its infancy in 2015.
  • On October 21st, 2015, the short, “Back to the 2015 Future”, premiered at Universal CityWalk as part of the 30th anniversary celebration. It features cameos from original Back to the Future cast members as well as sets from the original movies. It played five sold-out theatrical screenings, which you can attend... if you have a time machine. Otherwise you can watch it here now.
  • The Chicago Cubs were depicted to have won the 2015 World Series against a fictional team from Miami, whose mascot is an alligator (the Miami Marlins weren't a team at the time Part II was produced). In real life, the Cubs made the 2015 NLCS, only to be swept in four games by the New York Mets. Coincidentally, the last game of the NLCS took place on October 21st, the same day as the events in the film. However, the Cubs would win the following year's World Series against the Cleveland Indians.
