The Futureproof project is a model for engaging with the work of experiential futures using the format of improv theatre. It answers to the need for popularizing engagement with futures thinking identified in futures studies, and posits comedy and adaptability - two inherent qualities of improvisation - as areas of particular interest to the aims of futures discourse and experiential futures work. Key methods from its core disciplines of futures studies and improv are evaluated and combined to create a format for the creation and performance of improvised future scenarios that are accessible to a general audience. On a practical level, Futureproof outcomes include three public performances for sold-out crowds at the Bad Dog Theatre in Toronto, staged with a cast of professional improv actors and the engagement of a guest expert, each time representing a different discipline. The analysis and discussion of the experience suggests that both laughter and adaptability, key elements of improv art and the Futureproof format, can be usefully employed in the service of futures thinking and research. Looking ahead, the project also considers possible future iterations of the format, suggesting potentially advantageous design changes to its framework to orient it towards varied audiences.
