Let me start out by saying that I did a little post-movie interweb research on "All That I Need" and found several different numbers for the films budget, but found one page that the filmmaker himself said $40k. This statistic alone, and the fact that it was picked up by major theaters, should be enough to indicate its quality.
Don't go into viewing "All That I Need" expecting Brad Pitt and Charlize Theron with Ang Lee action, that isn't what it's all about. It's about capturing the raw emotions of individual people as they see the worst come out in their fellow man and their dreams collapse in front of them. I'm not going to ruin it, but it's shot in a documentary style of which the name escapes me at the moment. The subjects of the film are caught off-guard often and sometimes almost seem to be holding back in front of the camera. This is a good thing, as the pure feel of the situation is captured and the authenticity of emotion is conveyed with ease.
I saw it several weeks ago in L.A. I don't know if it's still in theaters, but I'm sure it will be coming out on DVD in a couple of months. "All That I Need" is a fun flick and one that you should check out.
