'Back To The Future' (1985)
Even if you haven't seen Back to the Future, you've heard of the DeLorean — the time machine Christopher Lloyd's character invented that sent Michael J. Fox's Marty McFly back into the '50s. The '80s sci-fi film is especially entertaining now that we've surpassed the year which Marty traveled to in the future (in the second film of the series). We are now officially living in the future, guys.
