The South by Southwest Film Festival (and concurrent Interactive conference) is underway in Austin, Texas, and DVD Talk's own Jason Bailey is on the scene, checking out some of the most interesting films of the fest. Check out his reviews of Bobcat Goldthwait's razor-sharp social satire God Bless America; William Friedkin's brutal, disturbing, and darkly funny Killer Joe; and Patton Oswalt and Johnny Knoxville as warring brothers in Nature Calls. SXSW is also showing some of our favorite movies from this year's Sundance Film Festival, including Sleepwalk With Me, Safety Not Guaranteed, and The Raid. Follow Bailey's SXSW progress on Twitter, and read his festival reviews in our Theatrical Reviews section.
