In her long career she played everyone from Margaret Thatcher to Queen Elizabeth, the Queen Mother.
She was also known for her big roles in several war movies. The most famous probably being "Ice Cold in Alex" (1958) with the iconic image below.
Other war movies included "Conspiracy of Hearts" in 1960 and "Operation Crossbow" in 1965.
Another great movie of note was her performance in the Cold War spy thriller "Danger Route" in 1967. A much underrated movie.
