Digital face replacement

Have you ever taken a picture of yourself and didn't like how you looked in it? Well, sometimes movies and TV shows have the same problem but they can fix it with something called digital face replacement!

First, they take a video of the actor’s face while they speak their lines. Then, they use a computer program to take the actor's face and put it on a different person's body.

This means they can use someone else's body and still have the original actor's face speaking the lines. This can also be used to replace an actor's face if they're unavailable or if they need to look younger or older.

Basically, it's like taking a puzzle piece of someone's face and putting it on another puzzle piece of someone else's body to make a whole new picture. Cool, huh?
