It's like a laboratory, a micro-society of real life, so it didn't look odd to talk about bureaucracy. In the school, in the class, there are already a lot of children from different ethnic backgrounds so the reality is there. I don't have to shove it in people's face. It's just there and it's normal.

It's cool that we got rid of that, but we got rid of everything - the encouraging pat on the back or even a hug which I find can be acceptable in some situations. I know that it's a sensible subject and that we're trying to avoid nasty things, but [you can] have as many rules as you want, there will still be stuff happening anyway.

My film is actually very critical of the level of French we're using back home. To have an immigrant from an ancient French colony come and do that is a little critical of our education system back home. Balzac is definitely over their heads. It's meant to be funny also because it would be also probably too much for kids in France, but kids in France would know who Balzac is. But, back home at that age, I guarantee you they don't know who he is.

If you're writing a screenplay from scratch, it involves a lot of creation. In this play, I had a strong main character and it involved some creation around him. That's what I like about adapting that particular play because I added some maneuvering space as a scriptwriter to invent my own things.

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.

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.

Some people around me said "Get a tux and live this and enjoy this" and that's what I did. It was a fun experience. On the red carpet, I was just behind Rooney Mara who I adore, and I had to not act too conspicuously because my girlfriend was there. Behind me, there was Glenn Close. So, it was kind of interesting.
