One day, out of irritation, I said, you know all of those years with the Royal Shakespeare Company, all those years of playing kings and princes and speaking black verse, and bestriding the landscape of England was nothing but a preparation for sitting in the captain's chair of the Enterprise.
Having played many roles of scientific intellect I do have an empathy for that world. It's been hard on me because flying the Enterprise for seven years in Star Trek and sitting in Cerebro in X-men has led people to believe that I know what I'm talking about. But I'm still trying to work out how to operate the air conditioning unit on my car.
William Shatner has one style. We have completely contrasting personalities. We're very good friends. I adore him, but we're very different people, so they were smart enough to write characters that reflected that.
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 came to feel very, very sentimental about those sets, which is ludicrous, because they represent everything which is transitory and insubstantial. It's absurd that one should feel sentimental about timber and canvas.
Encouraging people to believe in it was the most important thing of all. It's one of the reasons I was always uncomfortable whenever film crews came on the set to shoot things. I didn't want our make-believe to be exposed.
I don't do impersonations. I can do a wounded elephant! I can do a really good cow! And because of the amount of time I spent in North Yorkshire, I do a variety of sheep. All of which I will be happy to roll out for you!
The truth of the matter is, all of those guys on Star Trek: The Next Generation actually want to be me. These impersonations they do are just some way of trying to feel what it must be like to be me. And I understand that! Because it feels really good to be Patrick Stewart!
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.
I had come to the point when I realized it was unlikely that my film career was going to move beyond a certain level of role. And I was - because I had graphic instances of it - handicapped by the success of Star Trek. A director would say, 'I don't want Jean-Luc Picard in my movie' - and this was compounded by X-Men as well.
The knights of the theater represented to me not only the pinnacle of the profession but the esteem in which the profession was held. To find myself, to my astonishment, in that company is the grandest thing that has professionally happened to me.
