Earlier today, we reported that Warner Bros. is interested in Joaquin Phoenix playing the villain in their upcoming superhero sequel, Batman vs. Superman.  While much of the casting has yet to be finalized, we now have word of another screenwriter joining the behind-the-scenes mix in Oscar-winner Chris Terrio (Argo).  David S. Goyer penned the first draft of the film that finds Henry Cavill reprising his role as Superman, with Ben Affleck starring as an older, weathered Batman and Gal Gadot stepping into the shoes of Wonder Woman.  Terrio, who has a strong relationship with Affeck, has brought in to clean up the script before production gets underway.  Hit the jump for more.

As THR reports, Warner Bros. is bringing in the Oscar-winning talent of Terrio to shore up the Batman vs. Superman script.  Goyer is currently busy tending to other DC Comics titles, including the resurgent adaptation of Sandman. Terrio and Affleck previously collaborated on Argo, which earned an Oscar for Best Motion Picture and Best Writing of an Adapted Screenplay.
