A New York medical examiner said today that actress Natasha Richardson died of "blunt impact to the head."

Richardson, pictured here with her mother, Vanessa Redgrave, fell Monday during a private ski lesson in Quebec. Her husband, Liam Neeson, has been filming a new movie in Toronto. On Tuesday she was flown to New York, where she died yesterday.

Richardson’s colleagues and friends have been sending out their condolences.

Dame Judi Dench remarked, "She had an incredibly luminous quality that you seldom see, and a great sense of humor." Jodie Foster, with whom Richardson co-starred in "Nell," described her as "brilliant, beautiful, funny, talented beyond measure, as emotionally raw as she was razor sharp." She continued, "Tasha loved fiercely and that love continues in all of us who knew her. May Liam, her beautiful boys and her loving family hold her close as they move through this tragic moment."

Meanwhile, Lindsay Lohan, who played Richardson’s daughter in the remake of "The Parent Trap," celebrated the Tony Award-winning actress’s welcoming nature: "She was a wonderful woman and actress and treated me like I was her own." Mia Farrow also had kind words for the 45-year-old: "Tasha is irreplaceable. I cannot think of anyone kinder, more generous, thoughtful, smarter or more fun."

Such a shame that such a well-loved woman’s life has been cut so short.
