3. Star Wars Episode I: The Phantom Menace.
British actor Terrence Stamp said in an interview that he took a role in Episode I of Star Wars for two reasons: pressure from his agents and to work with Natalie Portman. When it came time to shoot his scene with Portman, she was nowhere to be seen. He asked Lucas where she was, and Lucas pointed at a piece of paper for reference. Stamp did not reprise his role, and he described the experience as “boring” and said that “actors prefer to work with actors.”
