Dominic: (On his kids' nickname for him) They call me Fathead. When I lost my hair, I became Stupid Daddy Fathead.
Dominic: (On his biggest weakness) I am always spoiling my kids. I can't help it. For the girls, it's dresses. I usually get my sons surf stuff...It's all them and only them. I'm devoted. I'm their slave.
Dominic: (on Joliet Prison) It's a very depressing, dark place, ... And the walls are just stained with sadness.
Dominic: You have to believe in hope, not only from an acting point of view but also from an audience perspective.
Dominic: (on getting the role in Prison Break) I was shocked, surprised and overjoyed and couldn't believe it when I got the part. Within a week that feeling turned into terror. I knew I had to pull it off. I had to make it work.
Dominic: I'm not into the techno funk thing. I like to sing along in the shower and not be overwhelmed by the noise. I love classical music and the bag pipes. I'm a bit of a dag, really.
Dominic: (on first studying acting) All I did was shout and scream. The instincts were there. I just didn't understand them. First and second year were a bit of a struggle.
Dominic: (being mistaken for a criminal in July 2006) This lady behind the counter started screaming like someone was robbing her. Before I knew it, two security guards came from nowhere and pinned me and dragged me, saying 'What's going on?' They eventually recognised me and asked for photos!.
Domenic: I was speaking American all day and then I'd get home and speak Australian. I just felt exhausted by going back and forth that I decided to speak it all the time. Now I just speak American.
