Scott Pilgrim: The Last Airbender
There are tons of mash-ups on the internet — most of them suck. Some of them don't. This is one of those that doesn't. It combines an excellent movie with an excellent cartoon for a delightful mash-up trailer.
This mash-up uses the audio from the live action Scott Pilgrim movie and scenes from the cartoon series Last Airbender, not that waste of film that M. Night Shalamalamadingdong directed. This mash-up is better than the whole live action Last Airbender movie.
