How Does Hollywood Achieve Those Special Effects?

Harry Potter and the Order of the Phoenix

A magical world like Hogwarts has to rely on special effects to present the audience with the original vision. Of course, a big side of that is Hollywood’s use of green screen. This is when they dress or cover something in green so that the color can be removed or edited later.


Here, we can see very human hands take books from actress Emma Watson. Once the hands are removed in post-production, it will look as though they are floating back into their place. It might not be ‘magic’, but it’s definitely magical!
