Warner will appear with Philip Glenister, Sorcha Cusack and Siwan Morris in a new play, The Feast of Snails, by Icelandic playwright Olaf Olafsson.
The Feast of Snails previews at the Lyric, Shaftesbury Avenue, from Feb. 8 and opens on Feb. 18. The play is about a successful businessman whose plans for a solitary evening at home with delicious food and drink is shattered by the arrival of a young stranger.
Warner's glory days were the 1960s, when his Hamlet and Richard II were the talk of London. Since appearing in a stage version of Robert Graves' novel I, Claudius (better known as a television series starring Derek Jacobi) in 1972, British audiences have only seen him in various film roles, including the role of bodyguard to the villain in "Titanic."
Warner's past connection with the RSC will be resumed, indirectly, as The Feast Of Snails will be directed by Ron Daniels, an Honorary Associate Director of the RSC.
