Michael Shannon's Stamp fear
A 2013 reboot of the classic superhero film series, Man of Steel will star British heartthrob Henry Cavill as Clark Kent while Amy Adams portrays Lois Lane. Kevin Costner and Diane Lane are also on board to star as Clark's parents, Jonathan and Martha Kent, respectively.
Michael Shannon cannot watch Terence Stamp's performance of General Zod in 'Superman II'.
The 37-year-old star is reprising the character in forthcoming Superman movie 'Man of Steel' - starring Henry Cavill as the titular hero - and he admits he is particularly intimidated by the film.
He said: ''I find that pretty intimidating, honestly. I think he pretty much nailed it. My girlfriend had it on. She was watching it out of curiosity and I saw it and said, 'You've got to turn it off. I can't watch that. I'm not worthy'.''
Previous performances are not the only problem he has with the film - he is also embarrassed by the motion-capture suit he has to wear.
He said: ''It's kind of embarrassing. It's nothing I would wear under normal circumstances!''
Despite the success he has found recently, Michael is unwilling to be too ''proud'' of his work.
He added: ''I don't see what more could be happening. Put it that way. Unless I receive a medial from the president.
''But you're always reluctant to get too proud of your accomplishments in this business. It can all go south in the blink of an eye.''
