The Star Wars creator released a statement about the death of his friend Carrie Fisher

“Carrie and I have been friends most of our adult lives,” he said in a statement to PEOPLE. “She was extremely smart; a talented actress, writer and comedienne with a very colorful personality that everyone loved. In Star Wars she was our great and powerful princess – feisty, wise and full of hope in a role that was more difficult than most people might think.”

“My heart and prayers are with Billie, Debbie and all Carrie’s family, friends and fans. She will be missed by all,” the statement concludes.

Fisher, 60, was aboard an 11-hour flight from London to Los Angeles on Friday when she went into cardiac arrest. Paramedics removed her from the flight and rushed her to a nearby hospital, where she was treated for a heart attack. She later died in the hospital.

Since her death, other members of the famous franchise have paid tribute to Fisher’s life and legacy.

“Carrie was one-of-a-kind…brilliant, original,” Harrison Ford said in a statement to PEOPLE. “Funny and emotionally fearless. She lived her life, bravely…My thoughts are with her daughter Billie, her mother Debbie, her brother Todd, and her many friends. We will all miss her.”

Her onscreen brother Mark Hamill, on the other hand, was speechless about the heartbreaking news of Fisher’s death: “No words #Devastated,” the actor tweeted alongside a photo of the two during their Star Wars years.

After him, several other Star Wars alums shared messages of love for Fisher on Twitter — including the actor who played Chewbacca.

“There are no words for this loss,” said Peter Mayhew. “Carrie was the brightest light in every room she entered. I will miss her dearly.”
