Jimmy Smits, formerly of TV's "NYPD Blue," and prolific British actor Christopher Lee, who donned Dracula's cape in the '50s, have been signed to join the cast of George Lucas's "Star Wars: Episode II," now filming in Australia. Smits will play Senator Bail Organa of Alderaan (the foster father of Princess Leia), while Lee will be a "charismatic separatist."
