It's an alterantive, promotional title used by some countries other than the US, but it is not the official name of the film. Per Wikipedia, IMDB, and the opening monoluge of the movie itself, the correct title of the movie is X2. The Marvel database has it down correctly as X2 as well.
Just because it's not the official title in the US doesn't mean it's not official. Bryan Singer has talked about the title before and as I said other sites use that too such as Rotten Tomatoes, Marvel Movies Wiki, Comic Vine ect... Doesn't really matter what title you use but this is an official title.
I wanted to ask you, now that I know the rules, can I please come back to the wiki. I asked around the community central and they said you cannot conduct a block where the remaining admins, which are you and Coleon, determine my fate.
Now that I know the rules, please can I come back.
You knew what the rules were before you were blocked. The terms of your propation (which you agreed to) were very clear. I said you would be immediately blocked if you caused any more trouble and I meant it.
I don't know who you've spoken to at Community Central, but if the staff members disagree with the way I'm going about this then they will speak to me.
Please do not contact me again. If you do so we'll simply forgoe the consensus and reinstate your permanent ban.
