Natasha Richardson hurt in skiing accident

Actress hospitalized after falling at Mont Tremblant resort

UPDATE: Natasha Richardson dies at 45

TORONTO -- Natasha Richardson has been moved from a Montreal hospital after suffering a serious head injury during a skiing accident.

A spokesperson at Sacre-Coeur Hospital said the actress, who was critically injured in a fall Monday at the Mont Tremblant resort, is on a flight to the U.S.

Reports in a number of outlets, including the New York Daily News and London's Evening Standard, said that Richardson, daughter of actress Vanessa Redgrave and director Tony Richardson, was being transferred to New York.

"According to the family's press agent, (Richardson) left Canada around 12:30 today," said Michelle Simard of the Sacre-Coeur hospital. "We have no information on Ms. Richardson's health condition, but the family should give more information by tomorrow."

Richardson's husband, Liam Neeson, left the Toronto set of Atom Egoyan's "Chloe" to be at her side, according to a source at Toronto's Filmport studios.

Richardson was skiing on Monday at the Mont Tremblant resort, about 75 miles north of Montreal, when she fell during a skiing lesson. The resort said the actress appeared to be in good condition after the fall but later felt unwell. She was taken to a local hospital and then to the Montreal hospital.

"She did not show any visible sign of injury, but the ski patrol followed strict procedures and brought her back to the bottom of the slope and insisted she should see a doctor," said a statement from the resort.

Mont Tremblant spokeswoman Catherine Lacasse said Richardson was getting a private lesson and that she said she was fine at first.

"An hour later she said she didn't feel well. She had a headache, so we sent her to the hospital," Lacasse said. "There were no signs of impact and no blood, nothing."

An ambulance was called and Richardson was taken to the Center Hospitalier Laurentien in Ste-Agathe and later transferred to Sacre-Coeur.
