Jerry Seinfeld has criticised 'Man of Steel' producers for ''glossing over'' Superman's secret identity.

The 'Seinfeld' star is a lifelong fan of the comic book character and was excited to see the latest interpretation of Superman on the big screen last year, however, he admits he was disappointed that a key theme in the Superman comic books - the hero's need to protect the identity of his human alter-ego, Clark Kent - wasn't given as much prominence.

In a Q&A with, he said: ''I was so happy that they made another Superman movie! I'm really reluctant to be critical of it in any way.

''But I thought the glossing over of the figuring out a secret identity and why he felt he needed one was a huge missed opportunity for that character.

''One of the most interesting things about Superman is the whole secret identity, so to me it was too much action/violence and not enough character study.''

'Man of Steel', which starred Henry Cavill as Superman, received a mixed response from critics but proved a success at the box office, taking in over $600 million worldwide.

The film has spawned a 2015 sequel which is currently in pre-production and will feature Ben Affleck as fellow superhero, Batman, and Gal Gadot as Wonder Woman.
