Movie magic behind the scenes incorporates many things such as costume design, script writing, and of course sound! But did you know that many of the sounds we hear – like crackling fire or horses trotting – aren’t actually real?

In fact, there’s a whole genre of behind-the-scenes sound artistry called “foley” that exists only to give the audience the sounds they think they should be hearing, based on what they’re seeing.

And they’re really good at making use of the least expensive option to give you the very best sound.

Here are some amazing examples of movie sound-magic that have absolutely fooled you before:

Who would have thought typical home and office supplies could make such incredible movie magic!
