Positivity about alternative body images oozes from this goodheartedly explicit documentary in which articulate burlesque performers discuss the transformative power of transgressing the boundaries of gender, performance and taste. At the heart of the often gaudy cabaret is the tender and touching love story of Mat Fraser and Julie Atlas Muz, whose in-bed interviews offer an insightful counterpoint to their confrontational stage acts – performed both together and alone. Those in search of safely exploitative titillation will be both disappointed and surprised; whatever their gender, it's the performers who wear the trousers.
