While Mark Ruffalo has become the first actor to truly play both Bruce Banner and his big green alter-ego The Hulk in Avengers Assemble, he portrayed the raging beast through the magic of performance capture, not a steady diet of steroids and steaks (or gamma radiation for the truly method). But he might be looking at a new exercise regime if he signs on to based-on-truth drama Foxcatcher for director Bennett Miller.

The Moneyball filmmaker has been developing the movie for a few years now with Capote writer Dan Futterman and E Max Frye.

Foxcatcher aims to tell the true story of John du Pont (Steve Carell), the heir to a chemical fortune who suffered from attacks of paranoid schizophrenia. During one such fit in 1996, he shot and killed his friend, Olympic wrestler David Schultz (Ruffalo, if he locks in a deal). While earlier reports had it that the movie’s title was inspired by one of du Pont’s factories, it was actually the name of the wrestling facility – Team Foxcatcher – that du Pont built on his sprawling estate.

Channing Tatum, who has been circling the film alongside Carell, is attached to play Mark Schultz, David’s younger brother and a fellow world champion wrestler.

With casting now seemingly falling into place, Miller is looking to start shooting this October in Pittsburgh.

In addition to the superhero film we talked about earlier (expect the review on April 20), Ruffa-Hulk Ruffalo has a few films set to arrive in drip feed fashion over the next couple of years, including sex addiction comedy drama Thanks For Sharing and magician heist thriller Now You See Me.
