movie script idea

Ok bear with me on this. I had this thought while taking the cramp train from work and I tot it would make an excellence movie.

Intro
Guy with wife and young kids. Everything good in his life. Then suddenly kanna accident. Ended in comma.

Rise of zombies
Some decades later, an unknown virus began infecting humans. And the became mindless zombie. Unlike the other zombie flick, these zombie aint stupid. Not those that would rush and chew. They are smart enough to run away when something goes bad.

Rise of machines
Machines were created to tackle the zombie issue. these biomechanical robots were so effective in dealing with the zombies, that zombies ended up hiding away. It din take long before the machines became sentient and sense that the humans are fearful of their effectiveness and seek to shut them down.

World war 3
Human began a pre-empt strike to take down the machine mother. some power mainframe la. it reacted by deeming humans as a potential zombie and commence warfare. this resulted in heavy loss to both sides, with zombie coming in to complicate things for the humans. It ended with borders to ensure peace to all. But tensions are ongoing

awaken the main protagonist
Within the borders, a bio-mechanical robot was attacking the zombie fraction and was alerted to see the humans. Human respond with attacks and chase it away. While the robot retreat, it saw a girl and froze. system error. Human then manage to seize this robot and take it back to their camp. Back at camp, they open the machine to get the spare parts and found a human body attached to it without any limps. Its eyes were closed with wires coming out of its brain.

The robot awaken and began killing, but when the girl appear again, it stopped. unknown why. the robot sees memories of its past and realise that it has been robo converted. the girl was his granddaughter whom look like his daughter.

It was then learnt that during the wall, the robots taken over a hospital that holds coma patients. and decided to bring them back to study human better. these human machine were more effective in killing as they were able to make creative deadly decisions. as such 100s of them were formed. they are part man and part machine now.

So now the main man, received calls from his master and directed him to go back. he over rides it and knew he has to end the war. so a renegade team is form that managed to sneak them into the main base.

As he fights his way thru, he faced off with newer machines that has zombies in them. They are far more deadly but has a witness that they desire to kill humans only. SOOOO he managed to win somehow.

As he approaches the mainframe, he is confronted by a higher level robot. It has both zombie and human attached to it. And the human is no ordinary human, but the president.

story goes that during the zombie infestation, the president was the one whom release the machines. He gotten scare and decided to terminate them, but they saw this first and captured him first. He was the first human machine and became part of the collective. it can be seen that he is not alone and was in fact in a room with 5 others. with 3 of them being zombies. The zombie collective wants to kill humans and the human collective is killing zombies. the collective doesnt see the protagonist as a threat as he is one of them.

he resent it and began fighting, but ultimately loss and died.

the human renegade see that they are losing, resented to fate and just then the zombies appeared and started attacking. zombies still see themselves as humans and wanted to end the machine wars.

and as i mentioned the zombies aint stupid, they were building military effort all along. and yes they won. as the human and zombies looked at each other, they know the next conflict is not far away. and the story ended.

the president then recap that the machines were part of a war effort that needs endorsing. when a parasite mutated and created the zombies, he used it as a leverage to go out on war. should effort be spend on cure, the infestation would have been controlled.
