Carrie Fisher has been praised by the cast of Star Wars for her last performance as Princess Leia in Star Wars: The last Jedi before she died last December.
Members of the Star Wars cast got to see a sneak preview of the eighth film in Los Angeles over the weekend.
The Last Jedi's cast acknowledged moving forward without her will be a real challenge, with director Rian Johnson saying: "I can't imagine anyone but Carrie in that part."
Luke Skywalker actor Hamill, who has been her on-screen brother since the 1977 original said: "I know she would be moved by the outpouring of emotion around the world because everybody reacted to it like a loss in their own family, but you're going to love her in the movie and I just wish she were here because we would be laughing right now, I'll never stop missing her."
"She's wonderful in the movie. She was such an integral part of the Star Wars family, there's no replacing her, we will always miss her but I do know she would want us to enjoy it, she would want us to be laughing."
Ridley, who returns as Rey, hailed Fisher's performance as "very moving" while Finn actor Boyega celebrated her for what he said was a much "darker" role.
"It's extraordinary," added Serkis, who plays Supreme Leader Snoke. "One of the things I came away with last night was the potency of what her character means to people, what it has meant for however many years now but also it's deeply emotional."
