A "premake" is when someone edits old movie footage to give us a look at what it would have looked like if newer movies had come out decades ago.

This is pretty impressive, and you can even prank your friends into thinking their favorite movies are remakes of films from the 60's. Here is a "premake" edit of Pixar's "Up".

The YouTuber that made this great fake trailer also uploaded a video explaining where he got the scenes from.

Check out what "Ghostbusters" would have looked like if it had come out in the 50's.

We are really glad they waited  until 2012 to make this next movie.
