If you look at the end of the movie [Monsegnor Lahzar], I give a lot of space to what the spectator can also imagine of what's going to be Bachir's life afterwards. So, there's the restraint part, and there's the fact that the story is happening in the school which allowed me to tackle all these subjects without making it too didactic, because in the school everything happens.

My film is in French. It's not something folkloric. It's who we are. There's this tension about immigrants coming in. Will they learn French? Will they adapt? In this film, I'm on the reverse side because Monsieur Lazhar comes from a society where French is also the second language.

If you read Herodotus, the first Greek historian 2,500 years ago, he was talking about that - about people mixing with other people. Sometimes it produces great societies. Sometimes it triggers war. But, we're not going to change that. I don't think so. We're living in nations that are state nations and countries.

I didn't want the film to be didactic, and this is tough because if you look at the list of issues, you have immigration, the education system, you have the grieving, you have suicide. I think what saved me were two things. I tried to do everything with some level of restraint and let the spectator make up his own mind.

It's the same challenge as with any other character, adults or not. You want to take time with the kids. You want to tell them in the audition that they have time to exchange ideas. I'm there. It's not someone else who does the audition, but I don't want to audition a thousand children.

I studied political science and international relations, so I never considered myself an artist.

I try to set up a playful atmosphere on the set so that they don't get tired too easily. They know it's work but they can also have fun, and when it's time to dig deep inside of them, they can go there.
