I’m sure by now you’ve heard that Wolverine will have three different endings, depending on where you see the movie. This isn’t a ploy to get you to drive all over the country to get to see all three of them. Rest assured the “movie” only has one ending.
You’ll sit through Wolverine in its entirety before the “alternate” bits happen. These very short endings come after the credit, and are reportedly all just ties in to whichever movie they decide to make next.
They’re not important to the story of the film you’ve just watched. It’s just the studio’s idea to open the door for the next movie in the franchise, of which there’s apparently three different ones.
I’ve spoken with a few people that have seen the endings already, and the feedback I’ve gotten is pretty negative about all three. They’re being referred to as “sucky ending 1″, “less sucky ending” and “ending that didn’t suck as much as the other two.”
I plan on checking out the film on Saturday morning, and will report back as to what I thought after that. I’m not super excited about it, because I didn’t really love the X-men trilogy, but the trailer looks decent enough to go check out.
