Like Daniel Craig, Oscar Isaac's uncle, and all of JJ Abrams' acquaintances, Ewan McGregor snuck into Star Wars: The Force Awakens with a minor role. After waiting two years for Abrams' call, McGregor's voice as Obi-Wan Kenobi can be heard saying, "Rey, these are your first steps." 

Some remarkable movie magic went into merging his voice with the OG Obi-Wan. "They got Alec Guinness to do 'Rey,'" says McGregor, explaining that the first word of his line was actually said by the original actor. "Which is extraordinary because he's not alive anymore."
