South by Southwest announced a nifty coup this morning, sending word that the world premiere of Matthew Vaughn's comics-hero send-up/fanboy wet dream Kick-Ass will open this year's film festival and conference March 12. Also booked for Austin: Saturday Night, James Franco's student-film documentary about life behind the scenes on Saturday Night Live. (Bill Hader teased the project last August in his Movieline Interview.) Cheers to them, and more titles as they become available... [SXSW]
