The Murder, She Wrote star portrayed Agatha Christie's famous detective in 1980 film The Mirror Crack'd, alongside a stellar cast including Dame Elizabeth Taylor, Tony Curtis and Rock Hudson, while other actresses to tackle the role include Dame Margaret Rutherford and Joan Hickson.
Disney bosses recently announced plans to reboot Miss Marple in a new movie showing her as a young woman, with Garner tapped to play the title role. Lansbury admits she is shocked by the news and can't understand how the concept could be successful.
She tells Britain's the Guardian, "Will you please tell me how? How can they cast this lovely young girl in that role? It doesn't make any sense at all."
