Many patrons know to stay seated after a movie based on a comic book or graphic novel ends. Or seems to.
Director Gavin Hood told the Associated Press that "X-Men Origins: Wolverine" has two endings, playing on separate prints.
Having seen "Wolverine" a day ago, this is what you need to know: One scene interrupts the credits but a second, more important one, plays after all of the credits have finished and you think the theater lights are about to come up. So stay seated and don't bolt for the exits. That scene sets the stage for what could be a sequel or a second prequel. You get the idea.
