As a movie studio, what do you do when the trailer for your highly-anticipated upcoming film reveals something it shouldn't? Modify the trailer, of course! Nevermind the fact that removing the evidence only serves to confirm that yes, that shot did mean exactly what you thought it did.
Bottom line: the trailer that is online now is not the one that was originally posted a couple days ago.
WARNING! REALLY MAJOR SPOILERS AHEAD! YOU HAVE BEEN WARNED!
Seriously, this is a big spoiler. Maybe not "I am your father" big, but possibly close. I couldn't even ethically make myself put the images on the front page of this blog, so you'll have to click your way to having part of the movie ruined. If you click any of the links below, I cannot be held responsible for the consequences. You have been warned
In the currently available trailers, the shot around time index 2:16 is Wolverine scratching his way down a wall.
However, when the trailer was first released, that same shot was something altogether different - SPOILER WARNING! Don't click this!!!!.
If you just clicked that second link, I'm so sorry. I won't describe what it is here, but it should be obvious if you look at what's in the picture, what's going on, and what's missing. I can't believe 20th Century Fox let that out, even if only for a short time. My guess - some editor's job is not as secure as it once was after this incident.
Rottentomatoes.com also shows the original image (SPOILER!) in their flipbook.
There. With as many SPOILER tags as I put in this post, you have no one to blame but yourself. And that dumb editor at 20th Century Fox.
