Second Childhood (1990)

Mark and his friends discover they've lived before. Not only that, they were famous and important people. Mark is elated - his father always wanted him to be "a somebody". Then Mark and the others find they are responsible for several of the world's big problems. So Henry Ford, Queen Victoria, Albert Einstein and Phar Lap set out to make up for what they've done. Never has a school history project been so dangerous, exciting - or hilarious.
