    Who are we and what do we do?

    Since National Theatre Live was launched in June 2009, we've broadcast more than forty productions live, from both the National Theatre and other theatres in the UK.

    Our broadcasts have now been experienced by over 5.5 million people in over 2,000 venues around the world, including over 650 venues in the UK alone. Past broadcasts from the National Theatre have included Danny Boyles' Frankenstein with Benedict Cumberbatch and Jonny Lee Miller, War Horse; Man and Superman with Ralph Fiennes.

    Broadcasts from other UK theatres include Coriolanus from the Donmar Warehouse; Macbeth from the Manchester International Festival; Our biggest single broadcast to date is Hamlet with Benedict Cumberbatch at the Barbican, which has been seen by over 550,000 people.

    How do we do it?

    Though each broadcast is filmed in front of a live audience in the theatre, cameras are carefully positioned throughout the theatre to ensure that cinema audiences get the “best seat in the house” view of each production.

    Where can you find us?

    The nearest venue to you is Emei 1958 Cinema, located at No. 360 Qingjiang Road East, Chendu, China.
