'Hey little girl! I need to borrow this… hoverboard?'

Hoverboard hoax – Zemeckis said on the film's behind-the-scenes featurette that the hoverboards (flying skateboards) used in it were real, yet not released to the public, due to parental complaints regarding safety. Footage of "real hoverboards" was also featured in the extras of a DVD release of the trilogy. A number of people thought Zemeckis was telling the truth and requested them at toy stores. In an interview, Thomas F. Wilson said one of the most frequent questions he was asked was if they are real.
