What movie promotion would be complete these days without some viral marketing? Seems more commonplace than not. And Warner Bros. is not going to go without for Man of Steel it seems. They have released a viral video tonight, the video is a warning from General Zod to the people of Earth. He has sent a warning that we are to turn over a citizen of Krypton to him. It is actually a pretty cool piece. Would be nice if you could make a little more out from the video though. Check out the video below, and keep an eye out for a new Man of Steel trailer tonight which should be premiering at the 2013 MTV Movie Awards.
