I read up on this and it seems they were having issues during the entire filming of this.

I dont why we are "revisiting" it since:

"It happens sometimes—but David is a very mercurial person, and that's part of why he's so brilliant. He almost reflects the movie. I did two movies with him, and I Heart Huckabees was so crazy, so all over the place, I think he kind of embodies intuitively whatever he's trying to make happen. It was just crazy, crazy stuff. We were always doing something, and then we'd get manic and crazy and I just flipped out on him. Then he flipped out on me. And you know, stuff goes on. But it's nothing. It's like family. If you have a big fight in your family, usually it's treated that way on the set. We don't want to misbehave; believe me, it's embarrassing. It's humiliating, you know? Because you just lose it. You act like a crazy person. [Laughs] But I adore David. I adore him as a talent. A lot of my friends said, "Well, you won't work with him again." I said, "Of course I would! I adore him, I love him. He's brilliant." "
