Extremely rare hero lenticular Mattel Hoverboard screen-used by Michael J. Fox as Marty McFly.
This Board is featured in the screenused.com Hall of fame:
Probably the most recognized props from Back to the Future 2 are the hoverboards. There are five styles of hoverboards seen on screen during the filming - Mattel, Pit Bull, Rising Sun, No Tech, and Question Mark. There is an additional orange Mattel hoverboard used by the other small child that was moving along the sidewalk with the little girl - however it is never seen on screen. There were several of each hoverboard created from either wood or styrofoam, depending on if the actors were carrying it, flying, or doing a stunt. The actors were rigged up with harnesses and swung from cranes over the water to give the illusion of flying.
This hoverboard is the one that Marty (Michael J. Fox) borrows from the little girl on the sidewalk. It was used throughout both Back to the Future 2 and 3. What is interesting about the Mattel hoverboard is that two different surfaces were created. Initially, a lenticular type material was used for the background color, which has a 3-D type look to it, with the other details hand applied. After a few of these were created, it was deemed more cost effective to create the more common "photo" Mattel hoverboard. The surface is a very detailed one to one picture of the original lenticular hoverboard surface.
Other details that are key to the Mattel boards are the footpads and the hole in the top for the handlebars. Many were created without the hole, assuming that detail may not be seen on screen. Additionally, in order to save costs, not all boards had a footpad. As filming progressed, hoverboards were scratched and broken, which led to them being literally thrown away. Before throwing them away, the footpad was removed and installed on another board.
This styrofoam lenticular Mattel hoverboard is very lightweight. It was used for shots of Michael J. Fox with the hoverboard screwed to his shoe, and was also used for shots of Michael handling the hoverboard.
