Sherlock stars Benedict Cumberbatch and Louise Brealey will take part in a the new series of Letters Live.
This celebration of historic letters, including Gandhi's appeal to Hitler for calm on the eve of World War II and Virginia Woolf's suicide letter, returns to London from March 31 until April 4.
The series is inspired by the books Letters of Note, by Shaun Usher and Simon Garfield's To the Letter.
Cumberbatch said: "Letters Live makes us pause and imagine the lives behind the letters read and the circumstances of their origin.
"It's a privilege to read this most ancient of communications live to an audience."
Brealey and Cumberbatch will be reading letters alongside various other performers from the stage, screen, music, art and literary worlds in London's Freemasons' Hall Theatre.
Brealey added: "Standing up there and speaking words written during the Second World War by Bessie Moore - words that were not meant to be spoken aloud even to her lover - is an electrifying privilege".
