With the South by Southwest Film Festival only a short ten days away, you'd think the programmers would be taking it easy. Wrong-o. Nobody rests on their laurels down in Austin, which explains why the SXSW crew keeps adding new movies, panelists and special guests! Here's the most-recent (although probably not final) batch of late additions:

Pop star James Blunt will attend the world premiere of James Blunt: Return to Kosovo, so be sure to bring those autograph books, ladies!

Director D.J. Caruso and "hot young" actor Shia LaBeouf will be in attendance for the world premiere of their Disturbia thriller, and will probably be talked into a post-movie Q & A session.

Actress Connie Britton and director Sarah Kelly will be here to introduce their cool-looking '80s-centric movie The Lather Effect, which also stars Tate Donovan, Eric Stoltz, Ione Skye, Peter Facinelli and Monica Keena.

Producer Elizabeth Avellan will stop by for a panel discussion on March 14th, and considering she's worked on movies like Sin City, Spy Kids and Grindhouse ... I just might have to stop by and have a listen.

Reign Over Me, a flick that sure looks like a true-blue "tearjerker for guys," will have its world premiere at SXSW on Wednesday, March 14. Written and directed by Mike Binder (The Upside of Anger), it stars Don Cheadle and Adam Sandler as former college roommates whose lives took off in decidedly ... different directions. (UPDATE: Both Cheadle and Sandler will be in attendance at this screening.)

More SXSW updates as they become available. And get ready for some serious wall-to-wall coverage of America's finest flm festival once March 9 hits the calendar.
