Over ten years, theatre creators David van Belle and Eric Rose worked with teams of talented artists to develop a body of unique plays using multi-phased devised creation processes. Three of these plays are printed in Three Impossible Plays for the first time—ephemeral, ‘impossible’ works partially documented in text and image. The three plays, The Highest Step in the World, The Last Voyage of Donald Crowhurst, and GIANT, were created and produced through Ghost River Theatre, a Calgary theatre creation company with a 30-year history of daring new work.
