She passed away on Sunday (03Jul11) after a battle with cancer.
Her agent says in a statement, "She will be remembered as a loving wife and mother, a cherished grandmother, a generous colleague and, always, a consummate professional. She will be greatly missed."
Massey was born into a showbusiness family - her father was famed Canadian-born actor Raymond Massey and her mother was British actress Adrianne Allen, while legendary director John Ford was her godfather.
She began her career on the stage and her big break came when she landed a role in Alfred Hitchcock's 1972 movie Frenzy.
Massey went on to star opposite her actor brother Daniel in 1973's The Vault of Horror, in which they played siblings, while her other major roles included her BAFTA-winning portrayal of a lonely spinster in a 1986 TV adaptation of Hotel du Lac.
She also starred in the 2002 adaptation of Oscar Wilde's The Importance Of Being Earnest with Reese Witherspoon, and landed a role opposite Gwyneth Paltrow in 2002's Possession, as well as appearances in British TV shows Poirot and Midsomer Murders.
Massey was awarded a Commander of the Order of the British Empire (CBE) for services to acting in 2004 and is survived by her second husband, Russian scientist Uri Andres, and her son, writer David Huggins, from her first marriage to actor Jeremy Brett.
