In his book A Funny Thing Happened on the Way to the Future, actor Michael J. Fox points out that some people take far too seriously what they see on the screen:
No matter how fantastic a move’s premise is, there are always a special few who buy in and accept the (craziness) at face value, like the hoverboard (seen in his 1985 movie Back to the Future). I’ve fielded more questions about hoverboards than any other aspect of the trilogy. Otherwise sane people were convinced that these devices actually existed, especially after (Director) Bob Zemeckis made tongue-in-cheek comments to the press about parent groups preventing toy manufacturers from putting them on the market (this resulted in hundreds of kids calling Mattel, demanding hoverboards for Christmas). Believe me, if someone had actually devised and manufactured a flying skateboard capable of propelling a surfer on an invisible wave of air, he didn’t let me in on the secret. It could have spared me from hours of dangling like a flesh-and-blood Pinocchio. Alternately strapped into every manner of harness, hinged leg brace, and flying apparatus the most sadistic special-effects engineers could devise, my foot stapled to that pink piece of plastic, I spent hours attached to metal cables, swinging from sixty-foot cranes, back and forth across the Courthouse Square set.
People believed those things existed? Apparently there is no boundary outside which some people will not stray when it comes to gullibility. If it’s on the big screen, it must be true. This is a variation of a greater truth: If it’s on the internet, it’s automatically true.
This is where we all roll our eyes.
