I was just looking at the Wikipedia entry for Superman Returns and noticed this:
"The working title for the sequel has been reported, and neither confirmed nor denied, as Superman: The Man of Steel. The focus will be on a tighter story with more villains and bigger action sequences.
Superman: The Man of Steel does have precedent - it was the title of the 6-comic miniseries which relaunched Superman in 1986 (and the main inspiration for our favourite TV show, since it introduced many of the themes in L&C). But "More villains and bigger action sequences" sounds like they are trying to make the story more like the comics, and less like L&C, though hopefully they will resolve some of the issues of their relationship such as Jason.
So... two questions, one about the title and one about the plot.
