The star, born Georgette Lizette Withers, passed away at her home in Sydney, Australia on Friday (15Jul11). No further information was available as WENN went to press.
Withers was working as a dancer in London's West End when she was asked to be an extra in the 1935 movie The Girl in the Crowd - but she ended up with a main role after director Michael Powell fired a lead actress.
She went on to rack up credits in films such as The Gang's All Here and One of Our Aircraft Is Missing, and also appeared on Broadway.
But she will be best remembered for playing Blanche in Alfred Hitchcock's 1938 thriller The Lady Vanishes, opposite Margaret Lockwood and Michael Redgrave.
Withers was the first non-Australian to be made an Officer of the Order of Australia and she was awarded a Commander of the Order of the British Empire in 2002.
She married Australian actor John McCallum, who helped create the cult TV series Skippy the Bush Kangaroo.
They had three children and lived together in Sydney until McCallum's death last year (10).
