What are you doing June 17th? That is the day "Robot Chicken: Star Wars" will premiere on the cartoon Network. It's sort of a crossover. Seth Green (OZ on "BtVS") is making it with the cooperation of George Lucas! It's a 30-minute stop-motion animated special which spoofs key scenes and favorite characters from the "Star Wars" universe. George Lucas will be in it as will Mark Hamill. I hope it lives up to the hype.
