This summer our community theatre company is putting on a production of 'Singin' in the Rain'... another one of those movies-turned-musicals. For the show we need some break-away doors for an actor to crash through and the only re-usable idea we can think of is to construct doors from 1.5" extruded foam and cut it into pieces. Than we would flex-coat the pieces and reconstruct the door within its jamb with tooth-picks to keep it together. Does anyone have another idea. We need two break-away doors that have to be used in 9 performances and 5 rehearsals, so they need to be pretty durable, though we would build back-ups.
