All the focus may currently be on Star Wars: The Last Jedi, but Mark Hamill is still willing and ready to discuss The Force Awakens, and one issue in particular. When asked if he was bummed that Luke didn't get a reunion with Han and Leia in The Force Awakens, Hamill answered, "Absolutely. In fact when I was reading [the script] I thought, if Leia was trying to mentally contact me and she's unsuccessful, she'll rush to his aid. She'll get close to him, get into some dire situation and that's when I show up for a big 'YAY!", save her life, then we rush to Han and are in the same position that Rey and Finn and Chewie are. But we're too late to save him but still witness it. That carries so much [more] emotional resonance into the next film for his wife and his best friend, instead of two kids that have known him for what...20 minutes?"
Hamill did go on to quickly follow that up with the fact that over the course of filming Episode VII and VIII he told J.J. and Rian Johnson, collectively, probably over "a hundred bad ideas", however his changes to Han's death scene actually seem better than what fans ultimately received. Said Hamill, "After the movies come out, I'm making a list of some of the more outrageous things I suggested because I look back now and go, 'What was I thinking?'
