Saying goodbye: The one scene in The Last Jedi that Mark Hamill can’t watch

In Star Wars: The Last Jedi, Luke Skywalker is reunited with his sister, Princess Leia Organa, for a deeply touching scene that was one of the emotional highlights of the action-packed sci-fi epic.

As it turns out, the scene was nearly as emotional for stars Mark Hamill and Carrie Fisher, who shared the screen for the first time as their characters since Star Wars: Return of the Jedi in 1983.

The 66-year-old actor sat down with ET’s Ash Crossan and opened up about the delicate scene, which saw Luke sweetly kiss his estranged sister — now general of the Resistance — on the forehead, and how the gesture came about organically.
