Variety reports that The Walt Disney Co. has recruited The Day After Tomorrow scribe Jeffrey Nachmanoff to pen three projects at the studio, including two for studio-based Jerry Bruckheimer Films.

Nachmanoff is doing scripting overhauls on Bruckheimer's adaptation of the Ubisoft vidgame Prince of Persia: The Sands of Time and Unnatural History as well as the LivePlanet-produced Liberty.

Prince of Persia tells the story of an adventurous prince who uncovers a dangerous artifact in a remote mountain kingdom and, with the help of an enemy princess, must stop a despot from unleashing a sandstorm that could destroy all mankind. Bruckheimer and his shingle acquired rights to the vidgame in a seven-figure deal in March 2004.

Unnatural History, on which Nachmanoff recently completed work, is an actioner about a family that becomes trapped in the Museum of Natural History and must fight to survive when the resident creatures come to life.

Liberty, another big-budget actioner, takes place after an electromagnetic pulse disables the infrastructure of the country; it revolves around a ragtag group of Americans who must use technology from the 1940s and '50s to defend against a foreign invasion. Ericson Core is aboard to direct.
