The actor, who played Rory Williams in Doctor Who, took over the role on Monday when the production celebrated its first birthday in London's Phoenix Theatre. Darvill previously played the role on Broadway and will stay with the London production until 10th May.
Once the Musical is based on the 2006 film of the same name, written by Enda Walsh. It includes many of the songs, including the Academy Award-winning Falling Slowly performed by Darvill in the play. It tells the story of an Irish busker and a Czech girl who meet through a shared love of music. The original production won 8 Tony Awards in 2012 and the London one has been nominated for six Olivier Awards.
Doctor Who News was invited to a special preview on Wednesday afternoon when Darvill and the company performed a number of songs from the musical.
