Tahmoh Penikett confirms himself via twitter that he's in the MOS. Some are speculating he's [BLACKOUT]Metallo[/BLACKOUT]. Real secret hush hush stuff. Thoughts? I had no clue about this rumor in the first place but apparently it's been around for a while. *Also On IMBD (take that as you will) his character is named Henry Akerdson. And another site brought it up that [BLACKOUT]John Corban[/BLACKOUT] uses that alias (minus the "d") when he assumes to be reporter at the daily planet in the Justice League Doom movie.
