Mark this day, my friends, because it is the first (and probably the last) time you'll see Kristen Stewart paired up with Nick Nolte.  It only happened today because we have some casting updates for you:

• Having gotten a taste for action in Snow White and the Huntsman,  Stewart is set to topline the gritty action thriller, Cali, written by Michael Diliberti (30 Minutes or Less).
• Three-time Oscar-nominee Nolte (Warrior) is in talks to join the drama Bitterroot, by debut director Chris Milk.

Hit the jump for more on both pictures.

Via Variety, Stewart will star in the Los Angeles-based Cali as Mya, one-half of a contentious relationship between two San Fernando valley lovers.  Mya and Chris have a tendency toward making bad decisions and following it up with worse behavior.  The plot has the duo selling a fake snuff film - featuring Mya as the victim - and then riding off into the sunset with their earnings.  Shit really hits the fan when Mya, presumed dead, must return to Cali to rescue her younger sister, but comes face to face with irate former business partners, "homicidal porn stars, stoner vet techs [and] an unstoppable killing machine in a cowboy hat." (On second thought, maybe Nolte would be perfect for this movie after all.) Stewart will earn her first producing credit on Cali, which is being shopped to directors with plans to start late this summer.

Also from Variety, Nolte is circling what sounds like an epic role for the veteran. Bitterroot, a Black List script by Michael Gilio, follows an aging Montana rancher who is scammed out of his life savings.  Unable to locate the swindler, the rancher packs up his guns and rides his horse into Bitterroot to get his money back.  Gore Verbinski and Jonathan Krauss will produce, with Annapurna Pictures fully financing the film, which Verbinski has been trying to bring to the screen for some time. Nolte can next be seen in Ruben Fleischer's Gangster Squad followed by Robert Redford's The Company You Keep.
