Stars of stage and screen have paid tribute to actress Natasha Richardson, who has died after a skiing accident.
Dame Judi Dench said she had a rare "luminous quality", and that Richardson still had great work ahead of her.
Ken Russell, who directed her in 1986's Gothic, praised her "ephemeral delicacy and intelligent beauty". Film-maker Sam Mendes hailed "a magnificent actress".
The New York City medical examiner's office said that 45-year-old Richardson had died of a blunt impact to the head.
On Thursday evening, Broadway, New York's theatre district, dimmed its lights for one minute as a mark of respect.
Richardson and Neeson married in 1994
Richardson's husband, Irish actor Liam Neeson, was embraced by fellow actors, including Matthew Broderick, following the tribute.
Richardson's mother, actress Vanessa Redgrave, and sister Joely Richardson, also an actress, also attended the event.
Earlier, the Oscar-winning director Sam Mendes, who worked with Richardson in a Broadway production of Cabaret, added: "It defies belief that this gifted, brave, tenacious, wonderful woman is gone."
Kevin Spacey, the director of London's Old Vic, said: "There are no words to express how tragic Natasha Richardson's untimely passing is for the theatre community.
"Her passion, devotion and talent will forever be etched on those who saw her work on the stage. The bloodlines of greatness were always there and she committed herself to every role she tackled," he added.
Richardson fell on a beginners' slope at the Mont Tremblant resort in Quebec on Monday.
The accident happened while she was taking a supervised skiing lesson.
The New York City medical examiner's office said on Thursday night that Richardson had died of epidural haematoma caused by a blunt impact to the head.
Medical examiner spokeswoman Ellen Borakove said the death had been ruled an accident.
Richardson died in a New York hospital, close to the home she shared with Neeson and their two sons.

The family were devastated by the death of their "beloved Natasha", her husband's publicist said.
Richardson initially showed no sign of injury but about an hour later she was taken to a nearby hospital after feeling unwell. It was later confirmed her injuries were critical.
Hollywood star Neeson, 56, flew from the set of his new film in Toronto to be with his wife as soon as he heard news of the accident.
He accompanied her as she was flown from Canada to Lenox Hill Hospital, in New York, on Tuesday.
Neeson, her mother and two sons, Michael, 13, and Daniel, 12, had gathered at her bedside.
Nip/Tuck actress Joely Richardson was also pictured visiting the hospital.
Richardson's death was announced shortly before midnight GMT on Wednesday. Neeson left the Manhattan hospital in a people carrier at about 2030 local time (0030 GMT).
Alan Nierob, Neeson's publicist, said: "Liam Neeson, his sons, and the entire family are shocked and devastated by the tragic death of their beloved Natasha.
