MTV Movie Brawl: Iron Man, Wolverine, Thor And Superman Continue On!

The MTV Movie Brawl continues this week with the launch of the official 16-film bracket. Eight epic match-ups are underway now, with four comic book movies currently slugging it out: "Iron Man 3," "Thor: The Dark World," "The Wolverine" and "Man of Steel." At least one of those movies will get knocked out of the competition this round, however, as Thor brings Mjolnir against the impossibly powerful Superman.
