The Bunker was a World Record attempt in 2013 for the longest improvised play. Produced in associating with SUDS, the only start point was a post-apocalyptic bunker: think Adventure Time, meets zombie movies, with the plot structure of Game of Thrones. Audience suggestions provided the stimulus for each hour.
Sarah Whillier was one of the core cast of 21 improvisers, with another seven guest improvisers, to complete the 100-hour show. It was performed in shifts of six hours at a time, and unfortunately was not awarded the world record due to an uncertainty by the judges as to whether the play was entirely improvised (it was!).
