I try to keep my characters raising more questions than giving answers. I don't want to leave too much on the table. I want you to have your connection and your secret understanding of the character.

I had been making a lot of family oriented movies, which I also like. But I still have a passion for the midnight audience and for midnight movies.

As a child, these colourful superheroes that could fly, or were horrifying like Ghost Rider and the Hulk, with this tremendous rage or these supernatural powers, provided an escape for me from my mundane existence, from my lack of friends or my inability to communicate well with people. They liberated me.

Having been a father for 19 years I realise fatherhood has changed me.

I love art, I love music. I can listen to Stockhausen and a very experimental, avant-garde approach, and I can listen to Beethoven and have a more classical, traditional approach. Why not be able to do that with film performance?

It's a family that's loaded with grudges and passion. We come from a long line of robbers and highwaymen in Italy, you know. Killers, even.

'Knowing' is one of those movies where you're going to get the spectacle, and you're going to have the entertainment in the grand science fiction tradition. But also, it will perhaps stimulate some discussion to help you sort out on your own where you might choose to go in terms of your own needs. Now, I say that without preaching.
