LOS ANGELES – Guillermo Arriaga is getting ready to crack the whip.

The writer behind Brad Pitt's fractured drama "Babel" as well as indie darling "Amores Perros" is working on "Tiger Hunting," a drama being developed as a potential Pitt vehicle by "The Wrestler" director Darren Aronofsky.

The story centers on an animal activist who must protect the small town he is doing research in when a tiger begins attacking its inhabitants. Pitt and Aronofsky have been developing "Hunting" under the radar since last year. It is set up at Focus Features.

Arriaga's other credits include "21 Grams," as well as "The Burning Plain," which he also directed.
