Yep, the courts (federal) have decided that the theaters must provide a way for deaf people to get the full movie experience (how they gonna experience the music? The other sound effects?) and that the cost of the interpreter(s) must be borne by the theater.
While I am all for the ADA as it was intended, at some point it has (generally caused by the courts, but not always) gone off the rails.
This is but one example.
