MovieMaker mag just released their 2008 Film Festivals issue and a lot of my favorite fests are listed, at least from what I can tell by this composite image. Fantastic Fest, Cinevegas, Ann Arbor -- yup, yup, looks good. I'll jet out to the local Borders tomorrow to pick up a copy and report back if there's more to talk about. I suggest you grab it off the stands while it's still around.
