Here's a nice featurette on the Tree of Life, with Christopher Nolan and David Fincher discussing Terence Malick's work.
If you like Malick, you'll like this: He's allegedly already preparing a six hour cut of Tree of Life, as well as a complimentary IMAX movie documenting the evolution of life.
Don't worry if that sounds too much. His next movie is a romantic drama. Which is promised to be "More experimental that Tree of Life".

Malick has also asked his crew to keep summer and autumn free for another possible feature shoot.
