Best evidence that Neo's phone call happens at the end of Revolutions.......
Sure people have posted stuff about the dates between Cypher and Trinity's conversation at the beginning of the Matrix and Neo's phone call at the end being 19 months apart.............this is circumstantial since we don't know exactly how long of a time frame the first movie lasted.....or the exact ammount of time between The Matrix and Reloaded.
People have also posted about the computer in "Enter the Matrix" being made in '99............which would put the Niobe/Ghost missions (that run in exactly the same time frame as Reloaded) in '99 since we assume that all the equiptment the Zion rebels use in the Matrix is the latest and up to date............why would they load inferior tools in their construct to take with them when they have access to the latest technology?
All that is circumstantial.........but may put you in the mindset that all 3 movies happen before the end of the first movie when Neo makes his phone call to the machines..........
How about this:
Neo's Phonecall at the end of the Matrix:
"I know you're out there.......I can feel you now"
Very last scene in Reloaded, Neo stops the sentinals:
"Something is different......I can feel them"
By Neo saying that something is different, he can feel them now.......doesn't this imply that he could not feel them before? If he only gained the ability to feel them when he touched the source, doesn't this mean he touched the source before he makes that phone call at the end of the first movie when he utters the line, "I can feel you now"? We all know that he didn't touch the source untill Reloaded..........so doesn't this mean Reloaded takes place before he makes the phone call at the end of the Matrix?
Nay-sayers have said, "but the cars in Reloaded are newer models"........I'm no cadillac expert so I can't guess the years of the models pictured in the movie.................however, those cars don't exist in the real world, only in the Matrix. Just because those cars weren't produced in our real world untill 2001 or 2002 doesn't mean that the Cadillac comany in the Matrix didn't produce those cars in '99.......it is only a V.R. simulation after all. This idea goes back to the tasty wheat conversation in the first movie.............how do we know if anything portrayed in the Matrix is the same as it was in the real world?
Also, in some scenes from the Revolutions trailers........Neo isn't wearing his robe from Reloaded, he is wearing the same clothes he wore at the end of the first movie...........which means he could wear those clothes throughout Revolutions then make the phone call.
I'm not committed to this theory...........but it does make sense........I'm taking it as a strong possibility...........the quotes from the end of both movies is what is kind of pushing me towards believing it.........
