“She’s like an irreplaceable member of the family, but the whole world feels that way. We are all sort of mourning her,” he said. “I always think of her in the present tense. I don’t think of her in the past. Any time you were with her it was just fun.”
Fisher died on Dec. 27 at age 60. She had been hospitalized for four days after suffering a heart attack while flying from London to Los Angeles on Dec. 23.
Hamill said having Lourd, who plays a small role in the upcoming Star Wars film, The Last Jedi, on the set helps Fisher’s legacy live on.
“You have that continuity there,” he said. “She’s so similar to her mother.”
Hamill joked that he knew Lourd was truly Fisher’s daughter when she was “an hour and a half late to the airport.”

And looking back on his friendship with Fisher, the actor said his sibling bond with her went beyond the big screen.
“Carrie used to drive me crazy,” he said. “We were more like siblings than I thought because we would have these huge fights. We wouldn’t see each other for months or even years and then you would see each other and remind yourself how much fun it was to be together.”
He continued: “Not only could she make me laugh but I could make her laugh. That was our goal.”
Hamill reprises his role as Luke Skywalker in Star Wars: The Last Jedi, out Dec. 15.
