David Leveaux's production of Rosencrantz and Guildenstern Are Dead is to extend at the Old Vic.
The production was due to finish at the end of April but will continue until 6 May.
David Haig also stars as The Player alongside Louisa Beadel, William Chubb, Josie Dunn, Matthew Durkan, Tim van Eyken, Wil Johnson, Hermeilio Miguel Aquino, Luke Mullins, Theo Ogundipe, Marianne Oldham, Evlyne Oyedokun, Alex Sawyer and Helena Wilson.
The show opened at the Old Vic at the beginning of March and was hailed by WhatsOnStage reviewer Sarah Crompton as "astonishingly funny", calling Radcliffe's Rosencrantz "a revelation".
The production marks the 50th anniversary of the play. Tickets for the extra week are now on sale.
Rosencrantz and Guildenstern Are Dead runs at the Old Vic until 6 May.
