I have resisted writing too much about filmmaking here, mostly because I'm not a filmmaker (or at least, not much of one). But when something like this comes along it just makes sense to share. FreeGeekery (a youngish blog, six months of age) posted an article today that lists out 15 Must-Have Freeware Programs for Filmmakers with a mini-review of each. There are some great finds listed here and they're even arranged by stage of production -- from screenwriting through storyboarding and budgeting, all the way through editing and post-production. A great resource for cash-strapped filmmakers.
