Directors = Ridley Scott, guy did blade runner. nuff said. OR Alex Proyas. Writer = Scott Frank, he wrote Minority Report. And he wrote Get Shorty and Out of Sight, he can write dialogue.
As far as cast keep neo, trinity, morpheus, the oracle and TANK!. Drop Smith, he died in the first one, fuck that "upgrades" bullshit. No new human characters, no "old programs" that dont fit with the first one. Just new villains that arent shitty looking fruitcakes with white dreadlocks.
As far as story, Neo has to wake people up. Like was promised at the end of the first. No overblown lame fight scenes where there is no sense of danger. The people in Zion should have some personality, not just a generic mass of hippies in burlap.
