Dark Side Knight v Super Jedi put together by Zach Snyder himself.
Zack Snyder posted the following mash-up trailer on his Vero account, bringing the world of "Batman v Superman: Dawn of Justice" together with that of the Star Wars universe. "Dark Side Knight v Super Jedi". I don't know how to get the embed code from Vero so I found where someone posted on youtube. Hopefully, it will stay up.
