The movie Antman was able to bring back Michael Douglas on screen from how he looked 25 years ago through the utilization of "digital equivalence."
The technology has been hailed as revolutionary by those artists working in the field of visual effects. It was also used for Brad Pitt in the Curious Case of Benjamin Button to make him look younger in the film.
This technology was also used on Donald Trump and, unfortunately he still was an @$$hole!
On a side note, I'd like to use the digital equivalence on myself so I can live happily in the Shire with Bilbo Baggins and all of the other hobbits who don't have to read articles about Donald Trump. That is why all those little guys are so jovial. They don't have the Internet or cable!
