Actor and writer Carrie Fisher was in “stable condition” on Sunday, two days after reportedly suffering a heart attack on a flight from London to Los Angeles.
Fisher’s mother, actor Debbie Reynolds, said the family would update the public with any further developments before thanking fans for their well wishes.
“To all her friends and fans, I thank you all for your prayers and good wishes,” Reynolds wrote on her official Facebook account.
Fisher, 60, has been hospitalized since Friday after going into cardiac arrest while aboard an 11-hour flight. After the aircraft landed, Fisher, best known as Princess Leia in the Star Wars series, was rushed to the Ronald Reagan UCLA Medical Center and placed in an intensive care unit.
Her brother, Todd Fisher, on Saturday said she was in critical condition.
Concerned friends and co-stars of the Hollywood star expressed hope she would make a full recovery.
“I am shocked and saddened to hear the news about my dear friend,” Fisher’s Star Wars co-star Harrison Ford, who played Han Solo opposite Fisher, said in a statement to the Associated Press.
The 74-year-old actor added: “Our thoughts are with Carrie, her family and friends.”
Others offered their hopes for the actor’s recovery on Twitter using the trending hashtag #MayTheForceBeWithHer.
Fisher had been in London filming the third season of the British television comedy Catastrophe and to promote her latest book, The Princess Diarist.
It remains unclear precisely when and how Fisher became unwell on her flight to LA.
The daughter of Debbie Reynolds and the late singer Eddie Fisher, Fisher shot to stardom when the original Star Wars was released in 1977. She revisited the role as the leader of a galactic rebellion in three sequels, including last year’s Star Wars: The Force Awakens.
In her first and best known book, Postcards From the Edge, she wrote about her turbulent relationship with her mother, as well as a cocaine addiction and mental health problems for which she had received electroshock therapy. She also recently started writing an advice column for the Guardian.
