Sony is in early negotiations with the writing team of Michael Brandt & Derek Haas to rewrite time-travel action-adventure “End of History” for Neal Moritz’s Original Prods.

Story’s centered on a scenario in which humans are no longer able to reproduce and are forced to travel in time to get the necessary gene to fix the problem. The original script by David Gleeson has time travellers going back to 12th century China, where they find themselves in the path of Genghis Khan’s army.

Brandt and Haas have teamed on scripts for “Wanted,” “3:10 to Yuma,” “2 Fast 2 Furious” and “The Double.” They are repped by WME.
