The theatre comprises a circular support structure 134 surrounding and mounted above a seating area 120 for an audience, and a plurality of arcuate screens 135 suspended from the circular support structure on rails for allowing movement of the screens about the seating area. A ceiling covering 155 is suspended over the circular support structure comprise a primary ceiling covering suspended from a ceiling support structure 160 and a secondary ceiling covering mounted above the ceiling support structure to provide a passageway for the egress of smoke in the event of a fire, the secondary ceiling covering overlapping the primary ceiling covering in at least the radial direction to prevent the ingress of light. The ceiling covering may comprise a mesh or flannel material. The ceiling support structure may be a circular truss. The screens may be formed of a polymer foam laminated with at least one layer of further material. The seating area may be mounted for rotation about a vertical axis. The circular support structure may be supported on vertical supports 132 distributed about its circumference with at least two vertical tension members between the circular support structure and the ground to enhance its rigidity.
