Legendary Pictures has acquired an untitled sci-fi pitch from writer Matt Cirulnick and producer David Manpearl.

In the story, humans have been subjugated after having lost a war to an enemy race. The first installment chronicles the start of the human uprising — led by a young man who escapes the prisons in which humans are being kept.

Cirulnick recently completed “Stones” for director Ridley Scott and Fox 2000 and is writing “The Lost Patrol” for Legendary. Cirulnick and Manpearl also are teamed on “Elysium” at New Regency.

Legendary, which partnered with Warner Bros. on “The Dark Knight,” is developing “Paradise Lost,” “Warcraft” and “Clash of the Titans.” Partner projects include “Watchmen” and “Ninja Assassin” at Warner Bros. and “Gears of War” at New Line.
