Earlier that same year, after witnessing a hit-and-run accident, Cruise called the paramedics and stayed with the victim, following her to the emergency room and then paying the $7,000 bill when he learned she was uninsured.

It's the kind of behavior that led Cruise's publicist to declare, "If I ever get in trouble, I hope Tom Cruise is nearby."
