Minchin, a Tony Award nominee and Olivier Award winner for penning the score to Matilda the Musical, and Schmitz (Travesties) star in the titular roles. Rosencrantz and Guildenstern Are Dead will run through Sept. 14.

Here's how it's billed: "In Tom Stoppard's evergreen comic masterpiece, the hapless pair's last days are chronicled; days largely spent trying to make sense of their interactions with other characters as the epic Hamlet unspools just off stage. In the hands of director Simon Phillips, the wit and playfulness of Stoppard's writing will be front and centre."
It has set and costume design by Gabriela Tylesova, lighting design by Nick Shlieper, sound design by Steve Francis and original music and musical direction by Alan John.
