Frequently Asked Questions
The most-asked questions about Back to the Future.
What is Back to the Future?
It is a beloved science fiction film series created by Robert Zemeckis and Bob Gale, centered on a teenager who travels through time in a modified car. The story explores how small changes in the past can drastically alter the future.
Who are the main characters?
The trilogy follows Marty McFly, a high schooler sent to 1955, and Doc Brown, his eccentric scientist friend who invents the time machine. Other key figures include Marty's parents George and Lorraine, as well as the antagonist Biff Tannen.
Where should beginners start watching?
New viewers must begin with the original 1985 film to understand the core plot and character dynamics before moving on to Part II and Part III. Watching in release order is essential because each sequel builds directly upon the events of the previous movie.
What vehicle allows time travel in the series?
The DeLorean DMC-12, a stainless steel sports car, serves as the primary time machine powered by a fictional flux capacitor. It requires 1.21 gigawatts of electricity to activate and reach speeds of 88 miles per hour.
What is the significance of the year 1955?
This decade serves as the primary setting for the first film, where Marty accidentally interferes with his parents' meeting and risks erasing his own existence. It establishes the central conflict of fixing history without creating a paradox.
Who is Biff Tannen and why does he matter?
Biff is a lifelong bully to Marty who evolves into a powerful crime lord in an alternate 1985 due to time-travel interference. His actions drive much of the plot in Part II, where his future self attempts to manipulate history for personal gain.
What is the flux capacitor?
This triangular device is the heart of Doc Brown's invention that enables safe passage through different eras when combined with sufficient energy. Without it, time travel would simply result in a catastrophic explosion rather than transportation.
