This might be vaguely predictable coming from me, but how about The
Matrix trilogy of films? The humans in the last bastion of mankind (Zion) are struggling to free the minds of 99.9% of humanity trapped in a simulated reality (the Matrix) by sentient Machines who use their bodies for food. It's the ultimate struggle for Man to free his kind from the Machines and liberate those trapped in an illusory System of control!
In the end...well, I won't spoil it (if you haven't seen it) but "Peace" and compromise are how conflicts are often resolved in the modern real world, so that might make a nice adendum for your essay.
Just a suggestion, check out the movies and their themes. It's all about freedom and its very philosophical.
