I won't spoil the scene's content except to say that it mainly serves to tee up next summer's X-Men: Days of Future Past, and that it builds to a reveal that, while nominally surprising, should come as a shock to no one familiar with the way comic books bend their own history to suit the whims of their fans.
Until its pro forma climax, The Wolverine commendably, and for the most part successfully, departs from the bigger-faster-louder logic of modern blockbusters. Wolverine, given healing powers by mutated genes and an unbreakable skeleton by the U.S. military, may be functionally immortal, but his adamantium claws require him to work on a human scale: He kills his enemies face-to-face, not by throwing a building at them. But that closing tag puts it back on familiar larger-than-life turf, which may be why it drew more whoops than the rest of the movie combined.
City Weekly critic Scott Renshaw, who along with several other colleagues confirmed that his audience went similarly bonkers for The Wolverine's mid-credits tag, wrote on Twitter that "Credit teasers are a microcosm of movie-news mentality: Potential is always more interesting than what's actually happening right now." Given how much of the movie's (presumably gory) violence takes place just out of frame (See "This Summer's Movies Have a PG-13 Problem") , perhaps it's appropriate that its biggest thrill comes from something unseen. But it also reveals the extent to which comic-book movies, and movies informed by parallel sensibilities, have transformed the methods of the movie industry's top-tier product.
Hollywood's early stabs at the comic-book idiom were apologetic, assuming that general audiences knew little of their titular properties beyond their basic iconography. But beginning with Tim Burton's Batman in 1989, the industry began to realize the power of motivating audiences who already had a stake in the characters. I'll never forget seeing the movie at an early screening filled with fans who'd bought their tickets through a local comic-book store, and the titanic roar that rose from the crowd as Batman's ship broke through the clouds and hung for an instant in front of a full moon, forming a perfect replica of the Bat-Signal. It was as if Hollywood knew we were there, knew we mattered. This movie was ours.
Twenty-four years later, the movie surrounding that moment has become redundant. Last weekend, Warner Bros., who released Burton's Batman movie, whipped Comic-Con's fans into a frenzy with a carefully staged, content-free presentation revealing that Superman and Batman will appear in the same movie in 2015. There's no footage, not even a script, but the mere idea was enough to send Hall H into paroxysms of ecstasy. Watch past the reveal in this fan-shot clip to hear a woman in the crowd exclaim, "I have goosebumps. I have actual goosebumps."
