In commemoration of the release of a 30th anniversary Back to the Future Blu-ray box-set, a short movie called Back to the Future: Doc Brown Saves the World (2015) was filmed with Christopher Lloyd reprising his role of Doc Brown. In the movie, Doc tapes a video message, explaining that he travelled to the 2040s in a rebuilt DeLorean, and discovered that inventions such as the Hoverboard and hydrated food will cause people to become massively overweight; even worse, a simultaneous glitch in every nuclear Mr. Fusion device on the planet will cause a nuclear holocaust that decimates the world's population. He subsequently travels back in time, and successfully prevents such dangerous devices from ever being invented, thus explaining why the future 2015 as seen in this movie did not come true in reality.
Crispin Glover sued the filmmakers, as he had not granted permission to use his likeness in Part II.
