Read the comic here.
In the Matrix movie, Morpheus has a long speech for Neo once he finally gets him on the phone: Yes. I've been looking for you, Neo. I don't know if you're ready to see what I want to show you, but unfortunately, you and I have run out of time. They're coming for you, Neo, and I don't know what they're going to do.
If only Keanu had more dialog than "Whoah", he might have come back with "Sorry, wrong number."
But that would have been a much shorter movie.
