Found via Danger Guerrero at FilmDrunk:
Basically, some hero took the trailer for John Carter, put a picture of Jay-Z (real name, Shawn Carter) over Taylor Kitsch’s face during the whole thing, and replaced his dialogue with lines from Jay-Z’s songs. It not particularly “good” or “seamless” by any means. It looks kind of like one of those little kid art projects where you make a doll by gluing someone’s picture onto the top of a popsicle stick, but that’s part of its charm. If it was any slicker, I probably wouldn’t like it. The only downside is that it’s so simple and perfect that now I’m furious I didn’t come up with it first.
You crazy for this one, jehanr.
