Michael Shannon may have had a role in the DC Cinematic Universe but he recently admitted that he fell asleep while watching Batman v. Superman: Dawn of Justice!

Shannon played General Zod in both Man of Steel and Batman v Superman, though the latter was more of a cameo performance. Despite his involvement in the film, he told Fandango recently that he nodded off while trying to watch it.

"People ask me about this all the time. Okay, I'll tell you the god's honest truth," Shannon said, of watching Batman v Superman. "Zack [Snyder] is gonna kill me for this - he's gonna kill me. I watched it once and I fell asleep ... I know, I know. I was on an international flight and I was tired."

Shannon has been hilariously blunt in the past in regard to Batman v Superman, admitting that he couldn't care less who would win in a fight between the two iconic superheroes.

"I'm so utterly unconcerned with the outcome of that fight. So profoundly, utterly unconcerned. I can't even come up with a fake answer," he admitted when asked by Vulture in March. "I guess I have to root for Superman because he killed me, so I would hope that he would continue his killing spree and become like a serial killer Superman. That's a new take on Superman. We'd all be in a heap of trouble if Superman was a serial killer. He could just wipe us all out. But then he'd be lonely."

Shannon has become a reliable character actor in the film industry over the past few years, and he admitted in his Fandango interview that he doesn't have much interest in blockbusters from Marvel or the Star Wars universe. So while we shouldn't expect to see him in any huge tentpole films anytime soon, he did reveal why he chose to do Man of Steel.

"When I did 'Man of Steel' I thought the story was interesting," Shannon admitted. "I thought it was relevant. It was about a civilization that destroys the planet they live on and goes looking for another one. Ring any bells? That's why I did it. I didn't do it because I felt I needed a big comic book franchise - I honestly thought it was a beautiful story."
