Superman Returns director Bryan Singer promises the planned sequel will have less character development and more action and adventure, thus explaining his "Wrath of Khan" reference made during this past summer's Comic-Con.
"What I was referring to was the fact that, when you do a first film like X-Men, for example, you're introducing a world and a set of characters," Singer told TodayOnline.
"Once those characters are introduced, once we've lived with them for awhile and we know them, when you get into a second film like an Empire Strikes Back (sequel to Star Wars: A New Hope) or a Wrath of Khan, you can make an action-adventure film and you don't have to bank all that time getting to know the characters. Now you can raise the stakes, raise the jeopardy and make a leaner, meaner movie."
