Did Michael Shannon appear in Batman v Superman, or was it just CGI?

Question

In "Batman vs Superman", the character Zod appears briefly as a corpse. Actor Michael Shannon - who portrayed Zod in "Man of Steel" - is credited as Zod, but in the actual cameo his face looks a little... off. I'm not sure if it's because his face is CGI'd in, or if it's makeup to make him look dead. Either way, Shannon would get a credit in the film credits. Granted, it's a testament to the state of CGI technology that I can't tell the difference.

Did Michael Shannon actually film the Zod scene in BvS or was it post-production work?

Answer 1

Michael Shannon Never Stepped Foot On Batman V Superman Set

In a recent interview with Metro UK, Shannon talked about his work on BvS.

“To be honest, I never went to the set of that movie ever,” he said. “I did some ADR, I recorded some lines that Zack [Snyder, director] wasn’t even sure he was going to use — like, creepy s— I’d be saying to Lex Luthor in the spirit world or wherever. I don’t even know if it’s in the movie or not. I do seem to recall a giant, rubber, naked version of my body.”

and,

Of course, fans already knew that Shannon was only seen in the film as a corpse, and that body was made from wax.

Jesse Eisenberg, who played Lex Luthor, told Conan O’Brien that the dummy was anatomically correct down to the last hair.

Studio ADI created the body double which used a headcast of Shannon and a body mold of Greg Plitt.
