The casting was expected. Falco had recently mentioned that she would be returning to Broadway, and Variety reported the Norman play as a likely vehicle.
Earlier Variety reports had a production of that drama coming to Broadway with Michael Mayer directing Camryn Manheim and Blethyn as daughter and mom. The bleak and humane play concerns a mother and her grown and ill daughter's wish to die.
The last time Falco came the Broadway, in Terrence McNally's Frankie and Johnny, the result was a box office success.
Mayer previously directed Falco in Side Man, the play that established the actress' theatre reputation.
The production will begin in October. Opening is in November.
Anne Pitoniak and Kathy Bates played mother and daughter in the original Broadway run of the play, which played the Golden Theatre March 1983-February 1984. Both actresses were Tony-nommed, as was the play and the director, Tom Moore. The production originated at American Repertory Theatre. The 1986 film starred Anne Bancroft and Sissy Spacek.
