This first one uses the audio from the trailer for the new G.I. Joe movie and clips from My Little Pony.
This one I particularly enjoyed, even though its silly, in general I think it's a cool when through creative editing you can change the whole tone and concept of a movie.
And this one was JUST posted in my subscription box so I'm adding it now. I think this is a cool blending of Disney's the Little Mermaid, with Doctor Who clips. It's not perfect but it's still really well edited I think.
Hope you enjoy!
