Two of the original stars of the hit film Willy Wonka And The Chocolate Factory will appear at the Edinburgh Fringe as part of a musical parody based on a Glasgow event that left parents fuming and children in tears.

Julie Dawn Cole and Paris Themmen, who played Veruca Salt and Mike Teevee in the 1971 movie starring Gene Wilder, will co-narrate the stage reading of Willy’s Candy Spectacular: A Musical Parody.

The show is based on the doomed Willy’s Chocolate Experience, which sparked headlines across the globe after being advertised as a “chocolate fantasy” where “dreams become reality” - but instead turned out to be a sparsely decorated warehouse where children were limited to a couple of sweets and a quarter of a can of limeade.

The cast of the parody was unveiled on Monday afternoon, with a bill that also includes Shelley Regner (Pitch Perfect series), Eric Petersen (Shrek The Musical), Nicole Greenwood (In Plain Sight), Wilkie Ferguson (Motown: The Musical), Cassandra Parker (Cabaret) and musicians Monica Evans and Chris Villain.

The show, created by US producer Richard Kraft and directed by Andy Fickman, will run at the Pleasance King Dome from 9-26 August.
