Written by Rodriguez, Alex Litvak and Michael Finch, the script follows a group of elite warrior types who are being hunted by members of a race of merciless alien trackers called Predators.

Brody plays a man who ends up inheriting the role of leader and is known as a hunter of men. Grace would play an accountant type whose unassuming facade masks a dangerous serial killer.

I'm a big fan of the Predator and Alien franchises. There's a lot of ways to tell a lot of stories about people and how they behave.
