When you consider all the stars I have managed mere submarines make me smile.

I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea.

I think a submarine is a very worthwhile weapon. I believe we can defend ourselves with submarines and all our troops back at home. This whole idea that we have to be in 130 countries and 900 bases... is an old-fashioned idea.

Our film examines the heroism courage and prowess of the Soviet submarine force in ways never seen before.

I've done four other films since 'Submarine ' so that's quite cool. It's just good to have people respect your work I've never had that before. Yeah my life has changed crazy. I'm a kid from a small town in south Wales I play my Xbox usually and all that sort of stuff and it's a whole new world.

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.
