Michael Shannon has revealed he had to be reassured by director Zack Snyder while shooting the new Superman movie, Man of Steel, as he felt ‘ridiculous’ in his motion capture suit.

Shannon stars as Kryptonian General Zod in the upcoming film and said he found it difficult in the beginning with the amount of CGI being used in the filming process – including his entire costume being added in post production.

Speaking to The Guardian Newspaper Shannon said: ''Literally the first shot I did, I was supposed to be coming out of a spaceship, which was basically some wooden stairs they'd built and painted neon green. I walked down them in my unitard, acting like I'm General Zod.

"After the take I walked over to the monitor and Zack was sitting there, and I watched it back and smirked.

"Zack said, 'What's wrong?', and I said, 'That's one of the most ridiculous things I've ever seen in my life.'"

However Shannon explains that Snyder was able to ease his concerns: "Zack's like, 'Yeah, but two years from now, it's gonna be one of the most badass things you've ever seen in your life.' And it is.

"But it takes a lot of faith, because the first day you're there and you wanna go home and cry, because you just think no-one's ever gonna take this seriously."

Man of Steel also stars Henry Cavill as Superman, Russell Crowe as Jor-El and Amy Adams as Lois Lane.
