The family of actress Natasha Richardson, who is in a Montreal hospital with critical injuries sustained in a skiing accident, have expressed their concern for her health and requested privacy, reports the Telegraph. The UK media is avidly following the sad story due to Richardson’s place in one of Britain’s great theatrical dynasties: her mother is Vanessa Redgrave, with whom Richardson had planned to co-star in a Broadway revival of Stephen Sondheim’s A Little Night Music. Her father was famed film director Tony Richardson; her grandfather was Sir Michael Redgrave and her sister is actress Joely Richardson. The 45-year-old actress is married to actor Liam Neeson, who was filming a movie in Toronto when the accident occurred. They have two sons.
