Well it seems some information has been leaked online about what is going on via IESB. One thing you need to know about IESB is they are Pro FOX and they seem very chummy with Tom Rothman. They also supported FOX in it's little Lawsuit against Warner Bros and 'Watchmen', that being said it doesn't surprise me that a guy who wants to be so cleverly called DPFan (Deadpool Fan) sends them a letter talking about the current situation. From what DPFan say's the re-shoots are being done to put more of the Character Deadpool in the movie. This make sense in the fact they want to make a spin-off movie, so they add more Deadpool to try and sell a classic Marvel character that they have changed according to Hugh Jackman. We also know that Ryan Reynolds is obsessed with the character and wants a spin-off film to work out. Here is what DPFan says:
We are told Ryan Reynolds was busy a guy in Vancouver during the extra time the production spent there shooting some added footage for his Deadpool character! Apparently most of the footage shot included Reynolds and Wolverine himself, Hugh Jackman.
This isn't your mother's cameo...Deadpool is full on! Reynolds will appear in the film even more than originally planned!
Do what you will with this information. I hope this movie is good, and I am interested to see what exactly FOX did to change Deadpool. All I know is the people over at Marvel are not too happy with it. No matter what the end result is, X-Men: Origins Wolverine should end up being a fun movie, with a few disappointments.
