Speculation immediately went to Michaelon Shannon playing Doomsday or maybe even some form of Bizarro.
However, now Michael Shannon clears the air by stating he was just making things up.
“I wasn’t there,” Shannon told the Daily Beast. “It’s a really awkward situation—I’m in the trailer for a movie that I didn’t work on.”
Shannon does confirm his voice will appear in Batman Vs. Superman and compares it to something similar to what happened with Jor-El appearing as a AI-ghost later on in Man of Steel.
“I went over and did some voice-over stuff because it’s like that ghost thing. But I don’t know if I’m supposed to say that. I get very nervous,” Shannon offered.
Regarding the flippers Shannon mentioned in a previous interview, the actor states he can't actually believe people took his answer as being serious.
“Somebody was asking me about this in New York and I made up some ridiculous bullshit answer about how my character Zod has flippers, and this went viral on the Internet or something and people have been asking me about that,” Shannon said with a "baffled" smile. “That is so obviously a complete bullshit story, right? But people took it seriously.”
Shannon does continue, with interstingly enough mention of Doomsday, offering he would come back even if he actually wore some sort of flipper appendages.
"Maybe they should add it, I don’t know! Maybe in Part 3, Doomsday will have flipper hands. I mean, look—nothing would make me happier than to work with Zack [Snyder] again, he’s hysterical and he’s a lot of fun to work with," Shannon said.
"Batman v Superman: Dawn of Justice" has a March 25, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves. Justice League is to follow directed by Zack Snyder as well.
Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
