It was a really cool moment to see Yoda show up in Star Wars: The Last Jedi and see him have a conversation with Luke Skywalker after all these years. I know a lot of fans were moved by that scene. I know I was! It was just one of those little reunions that, a few years ago, I never thought we would ever see!
If some of the fans were moved by seeing Yoda and Luke share a scene together, imagine what it was like for Mark Hamill when he walked on the set to shoot the scene with Frank Oz and the Yoda puppet.
Star Wars Legacy recently posted a video from the set of the movie that shows Hamill get all emotional when he sees Yoda for the first time on the set of The Last Jedi. It's kinda cool to see.
