Violence is a choice a man makes and he alone is responsible for it.

I always have been optimistic about humanity's future. Always. Even at the most dismaying of times.

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.

As time went on, I did campaign to lighten the character a little bit, to introduce some romance into the episodes, outside activities, horse riding and fencing and mountaineering.

When I'm meant to be standing in the wings, the only way to go is the ladies' toilets. It's the only time I've ever acted in the toilets.

Where can I go that would give me the same level of satisfaction as an actor?

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.
