Man of Steel Rumor: Lex Luthor is definitely in the movie, and has a connection to Smallville
Why do I care so much about these Lex Luthor rumors? Probably because he's one of my favorite characters in the DC Universe. I mean, have you guys ever read Lex Luthor: Man of Steel by Brian Azzarello? That's a terrific storyline, and takes away from the cheesiness that Luthor has been subjected to over the years. Apparently the character is getting the same treatment in MAN OF STEEL.
According to Harry Knowles over at AICN, Lex Luthor is definitely going to be in the film:
Lots of people have been wondering if LEX LUTHOR was going to be in MAN OF STEEL. The answer is apparently a very loud YES. Not only that the tone that Nolan/Goyer/Snyder are going for with the character is not the silly goofy Hackman Luthor... But an ambitious, ego driven and cold version of Luthor."
They also have news from the same source, who is said to be a person in the industry going by the name Indiana Smith, that a certain someone who has already played Lex is playing him again.
I'm going to advise this as a spoiler just in case you don't want to know, so.....SPOILERS BELOW!
Knowles says the name he was given is Mackenzie Gray. I will be honest. When I first read the name, I didn't recognize it. Then when his name was attached to SMALLVILLE, it was time to do a little more research. Gray played a Luthor clone on the series. When you look at him, you don't see the character, or at least I didn't (maybe a quick Google search will change your mind). They also uncovered video of Gray talking about playing a role in MAN OF STEEL, but he does know say what the role is. WHAT DOES IT ALL MEAN? The video is below, skip to the 1:00 mark.
