Sliding Doors is a film that Bill produced in 1998. It addressed a universal theme: how our lives are affected by the decisions we make. In this case, the story covers the two paths the character's life could take depending upon whether she catches a train. It stars Gwyneth Paltrow as the girl with "two lives." Most of us spend a lot of mental energy contemplating "what if I had done this instead." I know I do.
Lately, in listening to the radio and TV, I've noticed that the expression "sliding doors" has come into our conversations. As in "he had a sliding doors moment." It's not often that a film title becomes part of our language that everyone understands.
Yogi Berra thought about it too: "When you reach a fork in the road, take it."
