Jeffrey Blitz, director of the award-winning spelling bee documentary Spellbound, was in Washington to talk about his first feature film, the semi-autobiographical coming-of-age story, “Rocket Science.” He and I had a wonderful talk at the Georgetown Ritz hotel. We got off to a good start when we discovered we were both on our way to Comic-Con.

Most people would say that the lifetime period of greatest anxiety and misery is ages 13-15. What is it about that time of life that interests you so much?

You live an inwardly raw life at that age, you haven’t got an ability to protect yourself from your own emotions and the world. You are ripe –when you fall in love you really fall inlove, when your heart is broken, your heart is really broken, you don’t yet have the inner resoures to protect yourself or be anything less than completely that feeling.

It must be a challenge to ask kids to access and express emotions that are still unfamiliar to them. How do you work with these young actors?

The biggest part of it is casting. When you cast well you are casting someone who can access what needs to be accessed for that part. It was a low budget movie but we put whatever resources it had into casting. The great story about finding Reece is that we had looked for six months and finally HBO, who was financing, gave us a two week grace period, or we’d have to shut down. And then one day someone was walking through the production office with a bunch of tapes that had been sent in unsolicted. Normally, we would not have watched them but we were ready to try anything. Reece’s came from Vancouver and his agent sent it in. It was like when yiou meet someone you want to be friends with or fall in love, you don’t ask why It’s him, he thoroughly inhabits the role.

The big challenge was that in this case, we had a main character who stutters. It’s like learning a very difficult accent. Sometimes a performance suffers because the actor’s brain is working on the mechanical stuff their mouth has to do instead of what they need for the scene. We looked for six months, everywhere, we tried actual stutterers, but this character had a very particular kind of stuttering that is more amenable to the way of comedy, to set-ups and punchlines, it has a rhythm.

Our female lead, Anna Kendrick, came in very early into the process. After her audition, I wrote down Anna Kendrick is Ginny Ryerson, but because it was so early we thought we should keep looking. But she was one of the few girls we auditioned who could grasp everything she was saying, not just rattle off all those serious SAT words.

Boys and girls at that age seem to be from completely different species. How would you describe their differences and how does that affect their ability to communicate with each other?

We tried to get out of the idea that boys and girls are of completely different realms. Everyone in the movie is lost when it comes to love and romantic relationships and that defines them more than any differences. Ginny is very ambitious, not a typical girl role. They’re all kind of gender neutral in a way, all striving.

The adults in the film all seem to be dealing with their own difficulties. Despite the fact that the characters are surrounded by parents and teachers who theoretically have a commitment to concern for the kids, most of them do not seem to be capable of it. What is their role in the story?

We were not trying to make a comment about adults in general or say that adults are useless. If my main character is lost and all he needs to do is turn to his parents, there’s no story. It is so much more interesting if he has to solve things on his own. It’s not about debate, not about who wins; it’s about kids who are trying to grapple with questions that are bigger than they are. You can love but still not feel you understand it. The adults are childlike, all at the mercy of the mystery of love. The Violent Femmes (whose song is played in the movie) are so expressive of the anger of love gone bad. I love the idea that the adults’ idea of therapy is to do a cleaned up, dainty version of the songs that are roiling with such anger.

In a movie about the power of speaking to express oneself, why have a narrator? He seems to be omniscient, not just older and wiser. Who is he and what does he contribute to the movie?

Hal is a character who essentially has no voice and is struggling to find his voice. He has a fantasy of a voice like James Earl Jones. With a narrator, we had one character with no voice and one who is noting but a disembodied voice, a purely articulate voice. It shows the gulf between who Hal is and who he wishes to be. You are given Hal’s dream voice and confronted with his real voice. I love the idea of a torrent of words. When you grow up as a suttterer you are very aware of the power of words.

What do you want to do next?

I’m working on a documentary about lottery winners. It is another low budget scrappy project, just me operating the camera and producer/sound man. It is a great thing to go back and forth between big productions with a crew of 100 people and this little two-person movie. In a bigger production, you speak in a different language to the cinematographer and the production designer and the cast, many different languages all day long, saying the same thing over and over again. On this new film, I just put the camera exactly where I want to put it. I don’t have to say anything to anyone, I just start to shoot. There are two American myths about the lottery. One is the Protestant work ethic, it’s tainted, bad, and you’re cursed if you did not earn the money. The other is that it solves all your problems. The reality is that your sense of scale shifts, your sense of the money that you need or want shifts. If you have more money, you have more financial concerns. And family members and friends expect you to help them out.

Can you give examples of the kinds of movies and directors who have inspired you?

Hal Ashby — I watched his films again and again, the cinematography and production design. He has a masterful blending of absurd comedy and naturalism. His characters do outrageous things that are not of the real world and yet I feel like he’s someone I know. I did not want a Wes Andersen snowglobe artificial world. I wanted characters with real human emotion but exaggerated. I watch a lot of Billy Wilder films, the way he brings intelligence and humanity into whatever genre he was working in. I love the idea of being able to genre-hop the way he did. He brought his stamp to every one of his films, and I would love to be able to do that.
