“My youngest son, Kevin, who was four at the time, didn’t have his two front teeth. We were filming on the Hoth hangar set for some time, with the full-size Millennium Falcon. My two boys would come on set and play in the cockpit of the Falcon with Peter Mayhew, Harrison Ford, and Mark Hamill in-between takes.

For some reason Kevin just couldn’t say “Harrison.” One day Harrison picked him up and said, “Listen kid if you can’t say Harrison, just call me Peaches,” at which point Mark came over and said, “Well if you’re calling him Peaches, you’d better call me Cream!” From then on, in our house, Luke and Han were known as Peaches and Cream!”
