Dame Helen Mirren - Helen Mirren Breaks Theatre Initiative Record
The live broadcast of the production, which was beamed to movie theatres in the U.K. and America, attracted the largest audience for National Theatre Live's four-year-old venture.
The success has prompted talk of more screenings of the Peter Morgan play, which won Mirren an Olivier Award in April (13).
Mirren also played the reigning monarch in Morgan's The Queen. She won an Oscar for her portrayal.
