I really love Peter Weir -- I don't think all of his movies are amazing, but many of them are, and they're all really ambitious and unique. He never rests on his laurels. (Reminds me in that respect of George Miller, director of Babe and Mad Max)
[EDIT] To expand on my late-discovered love of the guy's work, the key figures in my slowly drifting toward being a bit of an actual film fan were all people I knew by name: Spielberg (Empire of the Sun, plus all his usual biggies), Don Bluth (Learning so young that a movie can hurt... and that can be a really good thing!), and George Lucas (first by hooking me on Star Wars, which got me into making-ofs and the craft of film-making and editing, the idea of the pastiche film which sent me chasing down influences, and then with the prequels with wanting, owing to my prior high levels of engagement with the franchise, to dig deeper into "... but why, exactly, are they so bad?" which was its own kind of education); but then, some time in the back half of my 30s, I discovered that a bunch of other films that'd been key on that journey were all by this one other dude whose name had previously failed to register. He was this fourth major figure in the early and middle parts of this journey, for me, and I didn't even know it!
