No one can resist the idea of a crippled genius.

I first had the idea of writing a popular book about the universe in 1982. My intention was partly to earn money to pay my daughter's school fees.

I categorically resist this idea that films are supposed to be autobiographical and the only stories you tell are about your own life.

He's crippled because I am.

The best part about being a genius is that you only have to prove it once on the IQ test. After that, you can just carry on like a complete idiot, and repeatedly exclaim "genius!" in obnoxious voices.

Even a genius cannot completely resist his Zeitgeist, the spirit of his time.
