This year's Otago University and Polytechnic capping show may be the last, if its subject matter has any truth to it.
The show, titled Capocalypse, is based on a prediction the world will end in December this year.
Students eager to perform in the apocalyptic Dunedin capping show have one last chance at tonight's final audition from 7pm in the College of Education auditorium.
Capping show executive producer Dan Hendra said Capocalypse comprised 18 cast members, of which a handful were main characters.
About 80 people were expected to audition for parts, he said.
The show also involves about 22 crew members and up to 100 others in various skits including the Sexytet, Selwyn Ballet and Knox Farce.
Despite its theme, Capocalypse is a comedy, in keeping with capping show tradition.
It includes Otago university and polytechnic references as well as familiar Dunedin landmarks.
"We usually base it around current social stuff and the university. We often have key characters in the university involved, like the proctor and Campus Watch, as well as key locations such as the Leith or clock tower," Mr Hendra said.
Capocalypse is set to run from May 9-19.
Otago's annual capping show began in 1894 and is the second-longest-running student revue in the world, behind that of Cambridge University in England.
