Becoming Luke Skywalker again was an emotional ride for Mark Hamill.

And the new documentary for 'Star Wars: The Last Jedi' shows a scene of Luke Skywalker seeing the new Jedi temple burning down.

Hamill says the scene was as heartbreaking for him as for fans to see. His tears were real tears.

Hamill's reunion with Frank Oz as Yoda was also intense.

'Star Wars: The Last Jedi' is now on Digital HD.
