Matrix 4 will be directed by Lana Wachowski. She will be writing the script as well. This gives her tremendous power to do whatever she likes. So she has made some plans for her upcoming movie. She wants it to be Absolute Crazy and she means it.

So he has good experience of working with Wachowski. He shared his experiences working with her. He said ” She comes with, ‘This is the character. This is what’s happening. This is the conflict. This is where I need him to be emotionally or psychologically or whatever plot-wise at the end of this sequence. What do you got in your bag of tricks to make it absolutely crazy?’ She’s one of those great people that she’ll tell us something and we’ll say, ‘Okay, we’ve got this.”
