I had this extraordinarily bizarre moment when, two Fridays ago, my missus gave birth to our second child at 11am and by the same time the following day I was sitting around a table with Ridley Scott, Russell Crowe and Leonardo DiCaprio in Rabat in Morocco, rehearsing a scene we were going to shoot the next day.

And I think in your 40s, you land a little bit, physically and mentally, you arrive at a place where you feel you've learned some stuff. Having children at that point meant I had something very useful to do for the next 20 years.

In the film industry you never really know if all the various ingredients will come together - sometimes they do, and sometimes they don't. As an actor, you don't have much control over those things. It's a director's medium in that sense. All you can really do is minimise the risks of being involved in something that might not work and look for something that also suits you.

My mother moved abroad when I was 11, my dad wasn't around from the time that I was a baby, so I was not the product of a family, but a product of observation - of watching what went on around me, of watching who I liked, what I didn't like, what I thought was good behaviour and what I thought was bad behaviour and tailoring myself accordingly.

The Peugeot is a very unthreatening car.

In the movie, you have to decide as an actor how you are going to give a character presence. You can't really move, walk, and talk like yourself. This creates something so you have to find something "other".

I think it serves the purpose of the film if the premise is that you're unsure of me because you've only ever really seen me play villains.
