The Solid Life of Sugar Water for Graeae, the company giving opportunities to D/deaf and disabled artists, and has stipulated that this should be respected in any revivals - the character of Alice is explicitly stated to be Deaf, and is required to be played by an actor with a hearing impairment, like Katie Erich in the Orange Tree's production. It's not specified what disability her husband Phil has, if any at all, but Adam Fenton has Tourette's. I'm not sure if the production integrating creative captioning to make it as inclusive for the audience as it is for the company is also a contractual requirement for staging it, but both productions I've seen have done so. So it's a play that foregrounds inclusivity, but the truth is it uses this as something of a red herring: Alice's deafness is occasionally referenced to dramatic effect, but the central tragedy the couple face is a - hopefully rare - potentially universal one.
