I will see 100 or 200 and I will take my time with them and I audition them for the two main roles. If I like what I see, but they're not exactly right for the role, I'll think well I have this other role that might work for them. Sometimes I will write a role for them because I want to work with them because they're so good.

Any place where you have to deal with many social actors like a school - you have the parents, the Ministry of Education, the school board, and the teachers - you need all kinds of sets and rules. You're trying to foresee anything that can happen and everything becomes really rigid. They don't want to talk about death because they don't want to overwhelm the children, but that has already happened, so you're not going to overwhelm them more.

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.

One particular night I was at the theater. I was not scouting for a project, but I was touched by this play by Évelyne de la Chenelière. I was touched by the character. I thought it was a rich character that could be rich enough for a movie.

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.

What I know is that if I was asked to teach mathematics in French for a week to young kids, I would do my homework and I think I could do a decent job. I don't think a degree in education would make me a better teacher. I sometimes teach in college. I don't teach for long periods of time, but I give workshops and I think I can communicate stuff. So, it's about communicating.

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