LOS ANGELES, Oct 18 — Ben Stiller didn’t think about how his family would react to his deeply personal documentary about his parents, Stiller and Meara: Nothing is Lost, until after it was finished.

“It was really kind of after the fact, once we got to the place where the movie was what it was, that I started to think about how it might feel to have it out in the world, and I had to kind of figure that out for myself,” Stiller told Reuters.
