If you have seen Star Wars: The Force Awakens, you’ve no doubt been tripping on the vision sequence. It appears Ewan McGregor might actually be Obi-Wan. One line is Alec Guinness and the other is Ewan McGregor apparently:
@maxreborules it was me originally but they replaced me with some guy named Ewan McSomething… 😜

If I had to wage a bet, Ewan says “Rey,” whereas the other is a clip pulled from A New Hope. Yoda’s line is from The Empire Strikes Back (as is Luke Skywalker’s “no”).
