Adapted into a TV show, two movie serials and reams of comic books, the property is now a 3-D feature that opens worldwide this month after spending nearly two decades in development, courting controversy with its casting and ending with a steep price tag of $130 million.

"It's been tumultuous," said Seth Rogen, star and co-writer.
