During the course of the seven years I played scenes with an oil slick, I played a scene with a grain of rice. Sometimes with indescribable creatures. I remember having a conversation with something which was simply a smell, that's all. It was part of our job.

I've often reflected on this in the past weeks as I've been following the presidential campaign: Very often, I thought it would have been great for both of these guys to sit down and be force-fed a couple of dozen episodes of Star Trek.

So far as education is concerned, it has had a significant impact on a lot of young people who turn to science as a much more exciting and interesting study than they otherwise might have found, entirely as a result of becoming involved with Star Trek.

One of the things that I've come to understand is that as I talk a lot about Picard, what I find is that I'm talking about myself.

I like things that are funny - in everyday conversation, in incidents that you see, in watching TV or watching film. Comedy has always had an impact on my life.

I've met actors where you think, if only you could just clean up your act and get it together, people would want to work with you. Some people are so difficult, it's just not worth working with them.

I know it feels like two steps forward and one step back, but we are making progress. In my lifetime, I have lived through one World War, I have lived through the end of Apartheid in South Africa, the pulling down of the Berlin Wall. I have experienced what I never thought I would have experienced, which is a pretty workable peace in Northern Ireland, and I experienced a unified Europe - until the Conservative government got its hands on the idea that in order to appease a few back-benchers they would hold a referendum, what a disastrous idea.
