This engaging and very well produced 2006 documentary (directed by Kevin Burns) about the Superman legend / phenomenon (call it what you will) tells the story of this superhero in all of its formats from its creation by Jerry Siegel and Joe Shuster right up to the Bryan Singer's own film 'Superman Returns'. "From comic books to radio shows. From TV to blockbuster motion pictures.". I found it very satisfying.
Since I was a boy I always loved Superman this is the first movie made of my hero and CGI was not around then everything was as normal as possible no wires ! Like I said I love Superman ! What a great hero , everyone in the world knows Superman !!
