Here's a video that, if anything, will make you realize just how often Hugh Jackman is forced to make the "I'm menacingly extracting my claws!" movement with his arms during production of every "X-Men" or "Wolverine" movie (in which the "give character large adamantium claws" button on Final Cut is used liberally in post).
That's because our good, clever buddies at FilmDrunk took the new "The Wolverine" trailer and replaced every "SHAWINNNGGG" (copyright "Wayne's World," 1992) sound that is made every time Wolverine's claws come out... with the sound of a slide whistle. And to be completely honest, we can't say it's any better or worse than before, it's just more noticeable. And hilarious.
There are pros and cons to the idea of the sound in the actual movie. For one pro, you have to think Wolverine would get even more enraged (in a good way — like a "Now you're really dead!" way) if he had to hear that noise every time he did it. A solid con, however, would be that we as audience members would have to listen to that sound 20-25+ times every Wolverine movie.
Either way, it's something to consider for the next go-around.
