Just last week, the South by Southwest Film Festival revealed the majority of its 2010 line-up, and now they've announced the guests scheduled to attend for their always-informative panels.

Jeffrey Tambor is returning with his popular Acting Workshop; Michel Gondry will turn up for a conversation about his work to date and his latest documentary, A Thorn in the Heart (playing there); David Gordon Green (Pineapple Express) will talk about his role in the success of HBO's "Eastbound and Down"; and the casts of Kick-Ass and MacGruber will each host a panel about their respective films.

I'd be remiss if I omitted two of the panels in particular: One sees our own Scott Weinberg moderating a horror panel attended by the likes of Ti West, Quentin Tarantino, Eli Roth, Matt Reeves and Ruben Fleischer, while another sees our own Erik Childress taking to task hyperbole in film criticism. We don't want to shamelessly promote either of them, obviously, but I will just say that I've heard Erik's will be "the best panel of the year" and "a total laugh riot!"

So... take that for what you will. Check out descriptions of the fest's main panels after the jump, and the rest over on their official website.
