LSD caused a lot of experimenting going on. And we're thinking, 'Wait a minute, what if we've got...' I always thought, 'What if some of those experiments actually had worked?' And what if they did? We probably wouldn't know that they existed. We heard that they were shut down, but we probably wouldn't be told if they succeeded.

Science fiction is an extension of science.

I had no intention of replacing Arnold [Schwarzenegger]. There were a few things that made me want to do the movie. They were the script which had a different direction to it, and it was a chance to do a very different Quaid. I didn't read the short story until I went to college.Reading the story had a different effect on me of how I pictured him to be and the tone of the story was different. In the story, he's a bit more of an everyman.

Some people will always be disappointed.

The three-breasted woman was very much at the top of my list in [original 'Total recall']. Like I said, I was fourteen! I remember Arnold [Schwarzenegger] pulling that big tracker out of his nose and freaking out about that. I remember going through the immigration booth where their face splits open with that heavyset redheaded lady. So there were a lot of these little moments that I remember.

There are plenty of directors who work with the same actors over and over, many more times than I have. Like I have worked with Bill Nighy more times than I have worked with Kate, but I'm not married to Bill Nighy.
