When Wolverine leaked, Fox went out of their to go around telling everybody that the leaked version wasn’t the final version, some scenes were unedited, the CGI wasn’t finished, etc. etc.  The first clue they were lying was that the running time for the finished movie and the leaked version were identical.  A tipster to AICN has since confirmed the obvious:

“Having seen the finished film, the mystery is solved: the workprint version IS in fact identical to the release print, sans effect and some audio work. It’s obvious that FOX is trying their darndest to keep this news from getting out, because it will eliminate most of the motivation for people who have seen the workprint to pay for a ticket. The finished effects are lackluster, to say the least – some really bad CGI work made me groan numerous times.”

Everyone was stealing it and saying it sucked, so of course Fox would claim it wasn’t the finished version.  “No seriously, guys, the final version is way different.  We just shot some fake scenes with a Black-Eyed Pea in them… to confuse you.  You really think we’d cast some fruity rapper guy as a cowboy?  What would’ve been the upside to that?  Haha, we got you good, you f*ckers!”
