The Chicest Vintage Photos of Helen Mirren
The National Youth Theatre
At 18 years old, a young Helen Lydia Mirren auditioned for the National Youth Theatre (NYT). Founded in 1956, the organization has produced a number of successful actors, including Colin Firth, Daniel Day-Lewis and Daniel Craig.
In this vintage image, Helen Mirren is in a reading for the NYT with fellow actors Michael Croft and John Nightingale. The celebrated actress credits her time with the NYT as launching her career. She landed her first big role in her third year of study.
Helen Mirren as Cleopatra
In 1965, Helen Mirren played Cleopatra in the NYT's production of Shakespeare's Antony and Cleopatra. Prior to this, Mirren had appeared in the NYT's 1963 production of Hamlet, and 1964's A Midsummer Night's Dream. However, it was her role as Cleopatra that landed Helen Mirren her first agent.

Speaking about the role, Mirren said, "I was in at the deep end. I loved the power and the passion of that role, and of course, it's always good to be Queen."
