No one knows much about Terrence Malick’s “Tree of Life” — it stars Brad Pitt, Jessica Chastain, and Sean Penn. It’s going to be weird and impressionistic. At least that’s what we get from the website it just sprouted, at www.twowaysthroughlife.com. Spooky orchestral music plays while the viewer can choose between “the mother’s way” and “the father’s way”–really just short, short clips from the movie that make no sense in their disjointed presentation. Malick’s childhood must have been nuts, that’s all you can think after watching this. Anyway. “Tree of Life” will be at Cannes, where jetlag is going to make it even loopier. The film will be an event, that’s for sure.
