Any moviemaking communities?

I would do as Terridax suggested once you have enough money. And if you're after some slightly more interesting footage that you maybe can't take yourself, then have a little look at ShutterStock.com. They have some amazing stuff.

Best of luck.

Oh, almost forgot, I've used http://www.stockfootageforfree.com sometimes. It doesn't have loads of stuff, and none of it is amazing, but it's free.
