When my dad took me to see a double-feature that we thought was all science fiction I experienced a Moment of Destiny. The first movie was fun but did not affect my life much (Dr. Strangelove, or: How I Learned to Stop Worrying and Love the Bomb) but the second one, ah ha! It was World Without Sun, Jacques Cousteau’s feature-length film When I saw that film I knew I was destined to become a marine biologist.
