The new son of Krypton is, Henry Cavill. Warner Bros and Zack Snyder (of Watchmen and 300 fame) are rebooting Superman and have finally cast The Man of Steel. The company sent out a press release this morning announcing it.
There are no hard details on the movie yet, but the casting is now done for the main character and from the above photoshopped image, it doesn't look too bad at all! Hopefully they're smart in their casting of Lois, Zod, Luthor, etc.
