I think I was really bored at school. I was quietly clock watching for years. I went to 10 schools because my dad was in the Army and we moved around a lot.

Usually, when special effects get in the way, it's because the story isn't strong enough. If you don't start with a strong screenplay, it's easy to fall back on special effects, thinking it's going to carry you. But it never works. It's just tiresome.

Blade Runner was the godfather of all these fantastic movies that occur today. What's frustrating is that we're short of really great writing and great ideas. Blade Runner was full of them.

I went to Art College and during the summer I made a movie with my brother. I got hold of a little camera, wrote a script and dragged my brother, Tony, out of bed to help me (which he did not like), so that we could shoot a film every day for six weeks. It was made for £65 and it was called Boy On A Bicycle.

I was always amazed about how much I could finally squeeze into a thirty second commercial.
