An actor said recently that, unless you're a parent, you shouldn't play a parent in a film. I don't know who said it, but I disagree. I understand that maybe there are aspects that you don't understand, or maybe this actor or actress had a really strong recent experience with having their first or second or third born child. I don't know. As a dad, I get that. I get that there is no love like it. But, at the same time, love is love.

I'm just a true Irish boy at heart.

From my experience, the only thing you can do is take what's written on the page and try, through your own curiosity and investigation, to make it your own and honor what the original intent was.

There was a part of me that felt afraid of people in Hollywood going: '**** Hollywood with their total lack of originality!'.

You consciously look after yourself, whatever that may be to you, whether it's going out for a few drinks and a bit of dinner, or just hitting the couch and watching TV, or going to the gym or yoga class. Just being aware that there's a potential for you to be in it and respecting wherever you find yourself is good enough.

I must say, I am thrilled with my fan base. For some reason some of them are quite young, so they are quite frightened. I remember when I did 'Click' and I'd see Adam Sandler's fan base. He's the guy that people feel that he's their best friend, so he's walking down the street and people sort of high five him and want to tell him a joke or invite him to come home and have a sandwich with them. Mine are not like that. Mine tend to go: 'Argh,' and look horrified. They shake and take a picture from a really long way away. I do feel I've got quite good, respectful ones though.

I had a list of about 35 restaurants, 25 of which were fast-food joints all around Los Angeles and I didn't get a quarter through the list. It just became me thinking about going to these places and wanting to enjoy the food and food just not being enjoyable anymore.
