So the passing of the torch is one of the oldest and most respected traditions where one older passes to a younger, a responsibility.
In this case, it's Luke being 'the beard' of [Star Wars: Episode VII](movie:711158). If you'll remember, course you do, Obi Wan was the beard behind the previous movies and now it would seem that Luke will be fitting into the role of the reclusive old master; similar to the Obi-Wan from A New Hope.
In the brief interview, Hamill said that he was there to:
Lend his support and grow a 'contractually-obligated beard'.
In thinking about Obi-Wan in A New Hope, he was doing quite a bit of this, lending support from behind an impressive grey beard; and obviously dying in a Christ-like fashion to save the galaxy.
As Sam Jackson said: 'They needed the push'.
I think it's cool that look is fitting into the role of Jedi master for [Star Wars: Episode VII](movie:711158). Do you agree?
Luke is the Jedi Master
