To be able to feel the lightest touch really is a gift.

So many of our dreams at first seem impossible, then they seem improbable, and then, when we summon the will, they soon become inevitable.

People may never understand this - and perhaps I should give up caring whether they do or not - but the idea of me playing Superman is so far away from what I was brought up to aspire to.

We live in a time when the words impossible and unsolvable are no longer part of the scientific community's vocabulary. Each day we move closer to trials that will not just minimize the symptoms of disease and injury but eliminate them.

I did my first apprenticeship when I was 15, then joined the union when I was 17. I worked every summer in high school and college.

What makes Superman a hero is not that he has power, but that he has the wisdom and the maturity to use the power wisely. From an acting point of view, that's how I approached the part.

Don't put a limit on what can be accomplished.
