Steven Spielberg's Amblin' Jul 15 2008
Amblin', Steven Spielberg's first film shot on 35mm, is available on YouTube (~25 min long). Binary Bonsai has more on the first real movie that Spielberg directed (which the director now dislikes).
Spielberg's first outing is all about humanity, love, feelings, innocence and all the other softness for which he has since become almost infamous. Whatever tech-lust Spielberg might have, goes on behind the lens, not in front of it. And despite moving on to do some pretty tech-heavy films (Jurassic Park for instance), he almost always keeps the human side of things front and center.
