English actress Natasha Richardson died Wednesday in New York after a head injury.

While on holiday in Canada, Richardson fell during a skiing lesson but immediately got up, claiming she was fine. Doctors say she suffered from an epidural hematoma from the fall, which causes bleeding between the skull and the brain’s covering.

Dame Judi Dench ,who co-starred with Richardson in a 1987 production of Ibsen’s Ghosts, said: “She had an incredibly luminous quality that you seldom see, and a great sense of humour. I thought she was a really great actress. It has been so shocking, really shocking.”
