The trailer for Matrix Reloaded will be shown before Episode II. Not that movie geeks needed any other reason to wait in line to see the film. May, and more specifically Memorial Day, has usually marked the debut of the summer blockbusters which have been marketed to death for the previous year. Typically kids have just gotten out of school, and it's the perfect time to release that PG or PG-13 flick which will turn away no one and debut with $50 to $80 million opening weekends. Studios are pushing back earlier and earlier into the summer, though, so we actually get Spiderman on May 3.
