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.

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.

I teach myself archaeology, I teach myself Spanish, and that's because it can be fun, it can be useful. So I keep studying. I read books because I still want to study. I don't want to stop.

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.

If youre writing a screenplay from scratch, it involves a lot of creation.

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.

Even if I knew that Separation would probably win, when they announced the film, I was thinking to myself "Oh! I want this! I want this!" And so, when we didn't win, I got depressed for about 20 minutes, and then I snapped out of it and enjoyed the rest of the evening.
