Theatre for the deaf isn’t a new concept, but it’s never been considered much of a growth industry, either. Still, Paris’s International Visual Theatre, catering to hearing-impaired audiences, has been around for three decades now, and this year, it found a permanent home for the first time. The theatre’s aim is “to build a bridge between deaf and hearing people by demonstrating that they can communicate perfectly with one another onstage as well as with an audience also made up of the deaf and hearing.”
