This brand new version is performed by four actors playing a minimum of 150 roles and contains every single legendary scene from the award-winning movie - including the chase on the Flying Scotsman, the escape on the Forth Bridge, the first theatrical bi-plane crash ever staged and the sensational death-defying finale in the London Palladium, besides many other favourite cinematic moments, including the memorable and controversial 'stockings and suspenders' scene!
