A new extended featurette for ‘Man of Steel’ has been released online and it manages to entice fans further for the film’s arrival. The 13 minute behind-the-scenes featurette is not only filled with exciting new snippets of footage from the film, but it also contains some pretty interesting interviews with director Zack Snyder, screenwriter David S. Goyer as well the actors in the lead roles of the film Henry Cavill, Russell Crowe, Lawrence Fishburne, and Amy Adams.

Despite all the images, trailers, videos and TV spots released, the one thing that most Superman fans have noticed but has not yet been addressed is the redesign of Superman’s suit.  If you’ve been wondering why the change, the video below explains it all.

It’s been known that ‘Man of Steel’ would do for Superman what ‘The Dark Knight’ trilogy did for Batman, and that is to ground the character in reality. According to Snyder, he wanted to “let the audience participate in the experience of being Superman without breaking the things that make him Superman. They were able to ground him and make him feel real.” Part of that included updating his suit. While Snyder was very partial to the cape, according to the featurette, it was his wife Deborah that suggested he ditch the underwear on the outside. “”The underwear is a leftover from Victorian era strongman,” says the director. “I probably looked at hundreds of versions with underwear but they fell by the boards ‘cuz I couldn’t make it feel consistent with the world that we were creating.”

As for the “S” on his chest, many have noticed that in ‘Man of Steel’ Supes is not the only character who brandishes that symbol as Russell Crowe also is seen having it. However, if you go back to the original ‘Superman’ movie starring Christopher Reeve, you’ll notice that Marlon Brando (who played Jor-El) also had the “S” on his outfit, so this is nothing new. Legend has it that Brando actually suggested that Superman’s family wear the “S” that would later been worn by their son. But in an added twist, Snyder does give us what the “S” stands for.

There’s lots more trivia to be had in the featurette below so get settled as you to go behind the scenes of ‘Man of Steel’!
